This second volume of Computational Nuclear Physics deals primarily with nuclear reactions; it thus complements the first volume, which concentrates on nuclear structure. Providing discussions of both of the relevant physics as well as the numerical methods, the chapters codify the expertise of many of the leading researchers in computation nuclear physics. The numerical methods discussed are embodied in a fortran code; sample input and test runs are also provided. All codes discussed in the book are included on a diskette; they conform to the fortran 77 standard. The subjects covered include: one-boson exchange scattering; the G-matrix in finite nuclei; the nuclear-matter effective interaction; nuclear collisions; the distorted-wave Born approximation; statistical models with angular-momentum coupling, time-dependent Hartee-Fock approximation for nuclear slabs; the Vlasov-Uehling- Uhlenbeck model; the friction model for deep-inelastic and fusion reactions; the quark model and nucleon-nucleon interactions; hadron-hadron and hadron-nucleus scattering.
