A Remark on High Energy Phenomena

Abstract

807A possible model which discriminates rr-N, K-N and N-N collisions in the cosmic-ray energy region is proposed. The difference in dependence of the mutiplicities on the energy of incident particles in rr-N, K-N and N-N collisions is discussed, which is due to the difference of the kinds of the incident particles. Experimental data obtained with nuclear emulsions are analysed by using our model. If our model is justified, the mean energy of the secondary particles of the rr-primary jets must be greater (about rwice) than that of the N-primary one, both in nucleon target and nucleus target cases.
