One hundred fifteen similar (p-p) interactions and 63 similar (p-n) interactions were selected from 1305 incidenis of proton interactions with nuclei in a 100-layer emulsion of ~450 mu thickness and 10 x 10 cm area bombarded by 9- Bev protons. Considering the number of proton collisions with the quasi-free protons in the nucleus as equal to the number of collisions with quasifree neutrons and excludtag the incidents of elastic (p-p) scattering, it is possible to obtain the cross section of inelastic (p-p) interaction at 9 Bev as equal to ~ 30 mb. The cross section of inelastic (p-p) interaction does not vary in the range 1 to 9 Bev. The total of elastic and inelastic cross sections is equal to 40 mb. The angular distribution of fast charged particles in (p-p) and (p-n) incidents is identical. The mean free path for 9-Bev protons in photoemulsion is (37.1 plus or minus 1.0) cm. The mean kinetic energy of fast particles inducing secondary interaction is 6 to 7 Bev for protons and 5 Bev for pi mesons. Particles emitted at larger than 10 deg angle form stars with n/sub s/ = 0.3 plus or minus 0.1. (R.V.J.)
