Neutron production by medium-energy (/less than equivalent to/1.5-GeV) protons in thick uranium targets

A model that includes fission for predicting particle production spectra from medium-energy nucleon and pion collisions with uranium nuclei has been incorporated into the nucleon-meson transport code HETC. A variety of calculated results obtained with this revised code for protons incident on uranium targets have been obtained and are compared with experimental data and with the calculations of other investigators. For incident proton energies /less than equivalent to/1 GeV, the calculated results are in good agreement with several, but not all, of the available experiments. 22 refs
