Abstract
Fundamentals of the cascade-evaporation model are briefly described, a nd the results of calculations performed in this model are compared wi th experimental data on interactions between H-1, He-4, C-12, O-16 Ne- 22, and Si-28 nuclei with energies 3.1-3.5 GeV per nucleon and photoem ulsion nuclei. It is shown that the model reproduces satisfactorily th e multiplicity distributions of s and g particles and correlations bet ween the multiplicities of these particles, provided that the mean num ber of emitted g particles does not exceed 20. The description of the multiplicity distributions of b particles, as well as the description of the correlations n(s)(n(b)) and n(g)(n(b)), is much poorer. It is c oncluded that the model can be used to describe the fast stage of inte raction, provided that the degree to which nuclei are destroyed does n ot exceed 40%. A successful description of the slow stage of interacti on is achieved for a degree of destruction below 20%.
