Multiple-source analysis of inclusive proton spectra fromNi +Ni Collisions at 876.5 MeV.

Experimental inclusive proton spectra ofNi+Ni at 15.1 MeV/u have been decomposed using three moving sources associated with, respectively, equilibrium, deep-inelastic, and preequilibrium processes. For the last, a new expression, taking into account the anisotropy of preequilibrium particles in the source system, has been applied. The high-energy part of the obtained angle-integrated proton spectrum has been compared with predictions of the diabatic dissipation model. [ABSTRACT FROM AUTHOR]
