Monte Carlo Calculations on Intranuclear Cascades. I. Low-Energy Studies

Nuclear cascade calculations of the Goldberger type have been performed using the MANIAC electronic computer. A three-dimensional relativistic treatment was used. The target nuclei were ${\mathrm{Al}}^{27}$, ${\mathrm{Cu}}^{64}$, ${\mathrm{Ru}}^{100}$, ${\mathrm{Ce}}^{140}$, ${\mathrm{Bi}}^{209}$, and ${\mathrm{U}}^{238}$. Incident protons and neutrons with energies between 82 and 365 Mev have been studied, but meson production was neglected in this energy range. Cascades initiated by about 1000 incident particles were followed in each case.
