pp. 606-613. (240 x 170 mm). 8 pp. 4 figs. Stapled pages. Very good. Summary: The energy distribution and polarization of muons and electrons are calculated assuming an interaction through a vector current of definite isospin character, and using form factors obtained by means of dispersion relations. The effect of the K* resonance is taken into account. The spectra, and to a lesser extent the polarization, are quite insensitive to this effect.…

Abstract: "A theoretical discussion of the spectra of the decay products of K/sub OMEGA 3/ and K/sub e3/ was carried out to obtain information on strangeness violating weak interactions. It is shown that there exists an angular correlation (dT/d cos alpha ) between the direction of the neutrino momentum in the center of mass system of the lepton pair and the direction of the pion. This angular correlation is quadratic in cos alpha independently of the structure of the form factors and provides the best means of identification of the type of coupling. Additional information concerning particularly to the form factor structure can be learned from the pion spectrum. A quantitative test, independent of the form factors, of the universality of the muon and electron interaction is suggested. Some quantitative properties of the electron spectrum in K/sub e3/-decay, independent of the form factor structure, were established. They are characteristic of the type of coupling. lt is shown how one can obtain the form factor from the knowledge of the electron spectrum if there is only one type of interaction." (- author).…
