Abstract
Neutron inclusive (singles) spectra were measured by the time-of-flight method at laboratory angles from 15\ifmmode^\circ\else\textdegree\fi{} to 160\ifmmode^\circ\else\textdegree\fi{}. When parametrized in the thermal model, a targetlike source was sufficient to fit the data at the largest angle, but in addition a half-beam-velocity source was required at the other angles, and at the smallest angles a projectilelike source was also needed. The model parameters are in general agreement with values obtained previously in fitting proton inclusive data. Comparison is also made with neutron coincidence data. Less phenomenological models---Fermi jet, Boltzmann-Uehling-Uhlenbeck, and Boltzmann master equation---are also able to account for the main features of the data.
