INTERACTIONS OF HIGH ENERGY PARTICLES WITH NUCLEI

The mechanism of the elementary particle production in nucleon-nuclei interactions in the energy range l0/sup 11/ to l0/sup 13/ ev was investigated. Data are given on the studies made with seven shower streams with a relatively large number of shower particles, formed during the nucleon interactions with nuclei in emulsions irradiated for 7 hr at 30 km elevation. The selected streams formed by neutral and charged particles were divided into two groups, one group having a narrow cone and symmetric integral distributions and the second having a considerably larger cone and larger number of charged particles. Diagrams are given of the angular distribution of shower particles in spallations of the investigated streams. (R.V.J.)
