Abstract

Using the detector ARGUS at the e+e- storage ring DORIS II, we have in vestigated inclusive momentum spectra of charged pions, kaons, and pro tons from decays of the gamma(4 S) meson. The kaon spectra have been m easured in two independent ways by coherently exploiting the detector' s particle identification capabilities, and by detecting decays in-fli ght. The extracted mean multiplicities for charged hadrons are 7.17 +/ - 0.05 +/- 0.14 pions, 1.56 +/- 0.03 +/- 0.05 kaons and 0.110 +/- 0.01 0 +/- 0.007 protons per gamma(4S) decay, where pions and protons from K(s)0 and LAMBDA decays have been subtracted.
