Photoelectric Counting Distributions for a Noise-Modulated System

Abstract

0 This experiment does not include neutral pion modes, which are expected to contribute another 30% or so 0 9 The good agreement with observed moments obtained when only low-energy photopion production data (<500 MeV) are used in Eq" (1) is similar to the result of Drell and Pagels [S 0 D 0 Drell and H. Pagels, Phys 0 Revo 140, B397 (1965)] 0 They computed the nucleon moments with dispersion theory by continuing the electromagnetic vertex in the nucleon mass and found that the low-energy contribution of the absorptive amplitude as given by the Kr oil-Ruder man theorem approximately reproduced the magnitude and isovector character of the nucleon moments. The 3, 3 channel did not contribute in their analysis but, in common with what is found above, the low-energy region gave approximately a correct result,
