Is the cascade mechanism of nuclear interactions realized in the high energy region

Experimental data on inelastic meson and nucleon interactions with nuclei have been analyzed within the framework of internuclear cascades to separate out the points, where the model is at variance with the experience and requires further improvement. It is possible to state, that at least up to 100 GeV energy at present there is no sufficient basis to postulate some essentially new internuclear interactions, although taking into account the increased volume and accuracy of experimental data, programs of cascade calculations require making more precise and large detailing. In particular, already at 10 GeV for a good agreement with the experiment it is necessary to take into account the processes, with which some cascade particles interact at once with an internuclear nucleon. In the region of energies of a hundred GeV without considering such processes it is possible to obtain the agreement with the experiment only rough-quantitatively in main characteristics with the accuracy up to factor 1.5-2
