Monte Carlo calculations on interactions of 300-Mev protons with carbon nuclei were performed using a Remington Rand Univac U.T.C. electronic computer. Nuclear cascades of collisions on bound nucleons were studied. The same calculations were then repeated with the assumption that each cascade nucleon has a non-zero probability (30 and 40%) of colliding with an alpha -cluster instantaneously formed inside the nucleus. The treatment of the cascade was carried out with the assumptions of a Fermi and of a gaussian distribution of nucleon momenta inside the nucleus. Results obtained were the percentages of cascades as functions of the number of collisions and of the number and nature of fast secondaries, the angular and energy distributions of the fast secondaries, and the excitation-energy distributions of the residual nuclei. The comparison of the results of the calculations with the few available experimental data gives the best agreement if the hypothesis of the existence of clusters inside the nucleus is adopted. The assumption that the momentum distribution of the nucleons is gaussian leads to absurd results concerning the energy spectrum of fast secondary nucleons and the spectrum of excitation energies of the residual nuclei. If a Fermi momentum distribution is assumed, the calculated spectra are reasonable and in agreement with experimental data. (auth)
