The theory of Geitler, Vanoski, and Messel postulates that collisions of primary nucleons with nuclear nucleons produce only one meson, hence the total number of mesons is determined by the number of primary particle collisions in passing through the nucleus. The relationship of the mean number of mesons produced to the primary particle energy, according to the multiple theory, is in good agreement with experimental data for primary particle energies of several Rev. However, experiments made with high- energy accelerators refute the theory. An attempt is made to find how the general concept of a nucleon cascade inside the nucleus agrees with the experimental data on nucleon recoil at primary particle energies of 5 to 20 Bev. The distribution of recoil nucleons from the spallation of emulsion nuclei by cosmic rays was analyzed as a means of clarifying the above problem. Studies of tungsten and aluminum spallation by cosmic rays showed that in aluminum spallation the mean energy of cascade protons is larger than in tungsten spallation, which is in good qualitative agreement with the concept. Quantitative calculations on nucleon showers according to Serber and Goldberger produced a larger number of aluminum spallation protons than was observed experimentally. Spallation of emulsion nuclei by 10/sup 10/ ev cosmic rays indicates qualitative agreement with the concept of cascade production by primary particles in the nucleus. 57 references. (R.V.J.)
