A microscopic model for estimating {ital n}{sub 0}, the initial number of degrees of freedom used in calculating pre-equilibrium nucleon emission from heavy-ion reactions, is presented. The model follows the evolution of the geometrical and phase spaces during the process of the gradual fusioning of the target and the projectile. A good agreement is found between the calculated values of {ital n}{sub 0} and the empirical values extracted from fits to nucleon spectra.
