Inelastic Scattering of Electrons by Protons

Abstract

DOOHERwhere px and p are the kaon and pion moments, respectively.We may use the branching ratios for V-+ I++I to check Eq. ( 19).However, most of these have not been measured accurately enough to provide any sort of test.Therefore, a mixing model must be assumed' to relate 8y and 0~.Once this is done, however, the mixing angles can be determined without resorting to perturba- tion theory, which is the usual method.For the mass- mixing model (Hr --e~) we obtain 38'&Hr&54'.The perturbation-theory result' is Oi =32'.A calculation based on 5V3 symmetry' yieMs Hy =39'.For the vector- mixing or current-mixing model, we obtain 45'&Hi &61' and 30'&8~&45'.The perturbation-theory result' is Oi --33' and 8~--2j.'.If we assume that the contribu-
