Erste Ausgabe seiner Bakerian Lecture. - "In 1927, with his second machine, Aston measured and codified the deviations in terms of the "packing fraction" (the positive or negative deviation of an atomic mass from an integer divided by its mass number). By plotting these fractions against mass numbers, Aston obtained a simple curve which gave valuable information on nuclear abundance and stability" (DSB). - Stempel auf Titel und Vorsätze erneuert.

Aston, building on the work of J. J. Thomson at Cambridge, developed modern mass spectrograph technology to investigate inconsistencies in the atomic weights of elements, discovering that "the elements are composed of atoms of varying mass, the atomic weight of an element being the average of those atoms comprising it. [Frederick] Soddy had coined the term isotopes for elements that are 'homogenous in chemical behaviour'. Thus, for example, no process of chemical analysis will differentiate between thorium, one form of uranium, and ionium, although each has a different atomic weight. Aston carried this investigation one very important stage further by demonstrating that similar conditions occur within the elements themselves [eventually identifying 212 naturally occurring isotopes by analyzing all but three of the non-radioactive elements in the periodic table.]. . . . The ultimate consequences of these discrepancies are far-reaching. The ration between hydrogen and oxygen is not 4:1, as it 'should be', but rather less; which means that when four atoms of hydrogen are transformed into one helium atom some matter is annihilated. In fact this is an example of the interchangeability between mass and energy which is postulated in Einstein's General Theory of Relativity" (PMM 412). Aston's "work on isotopes also led to his formulation of the whole number rule which states that 'the mass of the oxygen isotope being defined [as 16], all the other isotopes have masses that are very nearly whole numbers,' a rule that was used extensively in the development of nuclear energy." (ODNB) "Aston's achievements were kept continually before the scientific public by revised editions of his excellent book Isotopes. The included . . . a clear forecast of the power and dangers of harnassed atomic energy." (Gillispie) N. B.

(22,5 x 14,5 cm). SS. (385)-632. Mit zahlreichen Abbildungen und Tafeln. Original-Broschuren. Zu I: Erste Ausgabe dieser bedeutenden Bestätigung seiner Isotopenhypothese. - "In 1919, to test the neon isotope hypothesis, Aston built a positive ray spectrograph, or mass spectrograph with a resolving power of 1 in 100 and an accuracy of 1 (ppm). Aston adopted several methods to calculate the masses of the particles. In the case of neon, the intensities of the 20 and 22 mass lines implied a relative abundance of about 10:1, enough to produce an average mass of 20.2, the known atomic weight of neon. Neon was isotopic" (DSB). - Wohlerhalten. - DSB 1, 320; vgl. PMM 412.
