Abstract A new precompound Monte Carlo simulation model is presented. It permits unlimited multiple precompound emission for each interaction, may be used to give exclusive spectra and yields, and does not rely upon those exciton state densities shown to be inconsistent with the assumed two body transitions in the hybrid and exciton model formulations. Results of the new model are compared with {sup 90}Zr ({ital p},{ital xn}) single differential spectra for incident energies from 25 to 160 MeV, and for {sup 59}Co ({ital p},{ital x}) and {sup 51}V ({ital p},{ital x}) excitation functions for incident proton energies up to 200 MeV. The new model gives significant improvement over the hybrid model for calculation of excitation functions. Multiple precompound decay predictions are compared for the two models. It is shown that the restriction to two precompound nucleons per decay in the hybrid model becomes a poor approximation for incident proton energies above {approx_equal}80 MeV. {copyright} {ital 1996 The American Physical Society.}
