Abstract | In this work, we seek to develop a numerically fast method of determining multiplicities and double-differential cross sections of secondaries produced in the intermediate energy inelastic interaction of protons with atomic nuclei. We accomplish this by coupling global parameterisations of the relevant quantities of interest derived from BUU simulations to the GEM2 evaporative decay model. Issues associated with the mean-field representation of the incident proton are addressed by treating the spectrum of nuclear excitation levels as an equa-probable continuum. In general, we find good agreement with the ICRU63 results for incident energies in excess of 100 MeV. Below this, it is likely that a more careful treatment of the nuclear excitation spectrum is necessary. |
