Abstract

Data on the average multiplicity of neutral pions are presented for π-p, π-n and π-C interactions at 40 GeV/c, based on the statistics of 9 432 γ-quanta. A significant increase was found in the average number of π0s per inelastic event as a function of the number of charged particles for these interactions. Average momenta and angular characteristics of the γ-quanta are presented in both the lab. and the c.m. systems. It can be concluded that there is a plateau [in the -1<y*<1 interval] in the ( 1 σin) dσ dy*=f(y)*distribution of γ-quanta for π-p interactions and the value of the π-p cross section at y*=0 agrees quite well with the pp cross section at p=500-1500 GeV/c. This is in favour of the scaling hypothesis in the central region y*=0 for 40 GeV/c π-p interactions.
