Angular and energy characteristics of interaction between 9 Bev protons and emulsion nuclei, as well as the production of strange particles were investigated. The experimentel results reveal a better agreement with the cascade mechanism of nucleon-nucleus interaction than with the nucleon-tube model. The average energy loss in a single nucleon-nucleon collision was estimated to be (40 plus or minus l0)%. The size of a nucleon core is discussed. Through the optical analysis of nucleon-nucleon interactions the value r/sub c/ approximately 0.6 x 10/sup -13/ cm was obtained for the size of the nucleon core, while the fraction of peripheral collisions constitutes a 20%. Angular and energy distributions of slow K/sup +/ and pi plus or minus mesons were obtained. The production cross-section for K/sup +/ mesons with energy up to 140 Mev on an average emulsion nucleus is sigma = 5 plus or minus 2 mb. (auth)
