A phenomenological model of hadron-nucleus interactions is proposed which includes particle contributions from three sources: target-nucleon fragmentation, projectile fragmentation, and central-region ''pionization.'' The model is consistent with the energy-independent features of angular distributions and average charged-particle multiplicities. R = / (where n/sub s/ is the minimum-ionizing multiplicity on nuclei and n/sub H/ is the multiplicity at equal energy on hydrogen) is energy dependent and asymptotically proportional to nu-bar, the average number of collisions in the target nucleus. We conclude that, in p-p interactions, target and projectile fragmentation each account for 1.5 charged particles independent of primary energy, so that the energy dependence of resides solely in the central-region contribution.
