Deftly these authors had managed to obtain correct answers by non-covariant methods. . . With the successful completion of the magnetic momemnt and Lamb shift calculations, a solid beachhead had been established in uncharted terrain, the physics of radiative corrections" :: Abraham Pais, Inward Bound, pp.460-461. This paper represents a significant step in the research which would, 6 years later, result in Lamb winning the Nobel Prize in Physics. Willis E. Lamb was an American physicist who won the Nobel Prize in Physics in 1955 for research related to his discovery of the Lamb Shift. Norman M. Kroll was an American theoretical physicist known for his pioneering research in Quantum Electrodynamics, at the Institute for Advanced Study, went on to become a professor of physics at Columbia and later head of the physics department at UCSD.

Lamb attended the University of California at Berkeley for both his undergraduate and post-graduate studies. "For theoretical work on scattering of neutrons by a crystal, guided by J. Robert Oppenheimer, he received the Ph.D. in physics in 1938. Because of limited computational methods available at the time, this research narrowly missed revealing the Mossbauer Effect, 19 years before its recognition by Mossbauer" (Wikip.). "A Note on the Capture of Slow Neutrons. . . ," presented on November 9, 1936 and published in Physical Review in 1937, contributed to the first part of Lamb's thesis dissertation. The title of the dissertation was "I. On the capture of slow neutrons in hydrogenous substances. II. Electromagnetic properties of nuclear systems." "At Ann Arbor, I had heard Fermi lecture on the effect of chemical binding of a hydrogen atom on its scattering of slow neutrons. This interested me, and I began to work on related problems. It seemed that there might also be an effect of the binding of a hydrogen atom on the capture cross section for slow neutrons. At first I thought the effect would be large, but finally had to settle for a very rough estimate of the cross section for a very unlikely process: the radiationless capture of neutrons by bound protons to form deuterons, with the excess energy and momentum going into vibrational motion of the deuteron instead of a gamma ray. The normal capture process was very little affected by the chemical binding. Even today, this radiationless capture has never been seen, but I am still hoping that someday it may be. This work formed part of my doctoral thesis. The other part dealt with electromagnetic properties of nuclear matter" (Lamb, p. 136). "There is no greater tribute to Oppenheimer than the list of Ph.D.s he delivered, which includes Carlson, Christy, Dancoff, Kusaka, Lamb, Morrison, Snyder, and Volkoff" (Pais, p. 369). "Lamb was an American physicist who received the Nobel Prize for Physics in 1955 for his precision measurements of details of the spectrum of hydrogen. These included studies of fine structure and measurements of the Lamb shift, a key observational step on the road to the development of the theory of quantum electrodynamics (p. 203). Gribbin, John.

"Early theoretical efforts on heavy-ion stopping date back to Bohr (1940) who pointed out the importance of screening due to projectile electrons in the slowing-down of fission fragments, and to Lamb (1940) and Knipp and Teller (1941) who studied the problem of charge equilibrium for penetrating heavy particles" (Sigmund, p. 19). Niels Bohr (1885-1962), the renowned Danish quantum and nuclear physicist, had been working in Copenhagen on determining how fission fragments penetrate matter simultaneously with Lamb's experiments. In a letter that he wrote to Tom Lauritsen, a contemporary physicist, Bohr mentions this article specifically, writing: "Just a few days ago I received a copy of Physical Review of October 15 which, as you may have seen, contains a paper of Lamb, who has independently achieved many of the results arrived at in Copenhagen. I thought, therefore, that it might be best to my last paper in the Physical Review to add a small addendum like that enclosed and I should be glad if you will kindly see that it is introduced in the proof. . . . In Lamb's article I also found various references to experimental investigations of fission fragments which we have overlooked or not yet known in Copenhagen" (Bohr et al., p. 239). At the conclusion of Bohr's paper, "Velocity-Range Relation for Fission Fragments," he writes, "Note added at proof.â"After the present paper was sent from Copenhagen, we received here the issue of The Physical Review of October 15, 1940, which contains an article by W. E. Lamb on the passage of uranium fission fragments through matter. In main features the considerations of this article correspond to the arguments developed here and similar results are obtained" (Bohr, p. 275). Bohr, Niels.

First edition. THE LAMB SHIFT ? NOBEL PRIZE IN PHYSICS 1955. First edition, very rare offprint, signed by Lamb, who received a half-share of the 1955 Nobel Prize in Physics for this work. The Lamb-Retherford experiment of 1947 was the first to measure what is now known as the Lamb shift?the difference in energy between two energy levels 2S? and 2P? of the hydrogen atom?which had not been correctly predicted by the Dirac relativistic wave equation. ?The Lamb shift experiment was a landmark in 20th-century physics? (Biographical Memoir, National Academy of Sciences). ?After it was reported at Shelter Island, [the Lamb-Retherford experiment] became the point of departure for the renormalization program? (Silvan Schweber). Lamb (1913-2008) received his doctorate at Berkeley in 1938 under the guidance of J. Robert Oppenheimer. ?Unlike many of his generation of physicists, Lamb did not follow Oppenheimer into the wartime atom-bomb project. Instead, he concentrated on his specialisms ? microwaves and radar ? at Columbia University in New York, performing the experiments that culminated in the observation of the Lamb shift. This shift is a tiny difference in energy between two atomic orbitals in hydrogen, denoted 2S and 2P, distinguished only by their angular momenta. Quantum theories of the time predicted that these levels should have identical energies. The discovery that they did not demanded a fundamental theoretical rethink ? one that was initiated almost immediately by Hans Bethe. The Lamb shift thus became a cornerstone of the modern edifice of quantum electrodynamics (QED). This, the quantum field theory of the electromagnetic interaction, explains the shift as resulting from energy fluctuations in the vacuum that smear out the position of the electron in a hydrogen atom. This process has a greater effect on the Coulomb energy of the electron?s binding to the central proton at smaller radii (where the 2S state is most likely) than at larger radii (where the 2P state dominates). Today, precise measurements of the Lamb shift have tested QED to an accuracy of better than one part in a million? (Sargent). On Lamb?s 65th birthday, Freeman Dyson wrote, ?those years, when the lamb shift was the central theme of physics, were golden years for all the physicists of my generation. You were the first to see that this tiny shift, so elusive and hard to measure, would clarify in a fundamental way our thinking about particles and fields.? Not on OCLC or RBH. Provenance: Willis Lamb (signature on front wrapper). Lamb was born in Los Angeles, the son of a telephone engineer. He entered the University of California at Berkeley in 1930, where he earned a bachelor?s degree in chemistry (1934). Lamb continued at Berkeley as a graduate student in theoretical physics directed by J. Robert Oppenheimer, receiving his doctorate in 1938. In that year Lamb joined the faculty at Columbia University, New York, where he carried out research in microwaves and radar. His defence-related investigations focused on the problem of how to make shorter, higher frequency microwave sources for radar. It was this that would eventually lead to a Nobel prize in 1955. Lamb continued working in atomic spectroscopy and laser physics at Stanford University (1951-56), where he devised microwave techniques for examining the hyperfine structure of the spectral lines of helium, and then as professor at Oxford (1956-62). He returned to the US in 1962 as Henry Ford II professor of physics at Yale, joining the University of Arizona in 1974 until his retirement in 2002. ?In the second quarter of the 20th century, quantum theory faced some serious challenges, including unexplained details of atomic spectra and difficulties in calculating basic properties of charged particles. In 1947 Willis Lamb and Robert Retherford of Columbia University discovered an unexpected detail in the hydrogen spectrum, later called the Lamb shift, that became an essential clue in solving both problems. The measurement agreed with new calculations and was the first indication that the theoretical approach called renormalization could resolve the mathematical infinities that had threatened to derail the progress of quantum mechanics. ?By the 1940s, theorists understood a variety of phenomena that had small effects on the energies of atomic electrons, such as relativistic corrections and interactions between spin and orbital angular momentum. These effects showed themselves in the so-called fine structure of atomic spectra?the way that many spectral lines, corresponding to jumps between electron energy levels, are seen on close examination to split into groups of closely spaced lines. ?Lamb and graduate student Retherford wanted to measure the hydrogen fine structure by investigating two specific electron states. One was a relatively long-lived?S?state, with a spherically symmetric orbital, and the other was a shorter-lived?P?state, with less symmetry. Standard theory predicted that the two states should have equal energy but that applying a magnetic field should influence the states in different ways and induce an energy difference between them. ?The team sent a stream of electrons at right angles into a beam of hydrogen atoms, exciting a few of them into the?S state and also deflecting them slightly from the main beam direction. The excited atoms passed through a region containing both microwave radiation and an adjustable magnetic field and then hit a metal target. The excited atoms would then drop back to the ground state, emitting electrons that the team could detect as a current. The key to the experiment was that if the magnetic-field-induced energy difference between the two states was equal to the energy of the microwave photons, then the long-lived?S?state would absorb a photon and turn into the short-lived?P state. These atoms would drop back to their ground state before reaching the target, and the current in the detector would essentially vanish. ?By plotting the critic. Signed.
