A master equation is incorporated in Feshbach, Kerman, and Koonin model calculations of statistical multistep compound (MSC) emission. Damping [Formula Presented] and [Formula Presented] functions which describe the particle-hole annihilation process are derived. The MSC cross sections are calculated with the master equation. The effect is found to be large at lower energies for light nuclei, but not significant when the incident energy is above 20 MeV. The difference between a closed form solution and the master equation result is masked by the large multistep direct and evaporation components.
