Unitary Models of Nuclear Resonance Reactions

Physical Review, 1967
While most reaction theories are formally flux conserving, the kinds of models and approximations used to specify the $S$ matrix for resonance reaction processes are often of doubtful unitarity, particularly in the overlapping resonance region. To investigate the consequences of unitarity in this domain, several classes of simple analytically specified

Computer simulations of fragmentation in nuclear reactions: A semiclassical model

Physical Review C, 1987
A semiclassical model is used to perform numerical simulations of the production of nuclear fragments in both proton- and heavy-ion-induced reactions. The Pauli principle is incorporated by means of a collision term, as it is in the Vlasov-Uehling-Uhlenbeck equation. The model goes beyond the Vlasov-Uehling-Uhlenbeck equation by propagating on an event-

Computational model for nuclear reaction studies: Quasiparticle dynamics

Physical Review C, 1988
A computation model for nuclear reaction studies which is based upon a momentum dependent interaction between quasiparticles is extended to include collisions between the nucleons. The model is first used to examine the time scales involved in fragment formation at intermediate energies, both as a function of bombarding energy and impact parameter. The

Hybrid Model for Pre-Equilibrium Decay in Nuclear Reactions

Physical Review Letters, 1971
Ideas from Griffin's exciton model are combined with those from the nucleon-nucleon scattering approach to nuclear transition times to provide a simple closed-form expression for predicting pre-equilibrium decay phenomena, including variation of pre-equilibrium emission with target mass, excitation energy, and initial particle and hole numbers.

Surface effects in the exciton model of preequilibrium nuclear reactions

Physical Review C, 1985
Surface effects on direct particle emission in the exciton model of preequilibrium nuclear reactions are described in terms of the mean effective well depth in the region of the first target-projectile interaction. A simple parametrization for this quantity as a function of the bombarding energy is derived, and its predictive ability is demonstrated ...
