Folding models for elastic and inelastic scattering
The most widely used models are the optical model potential (OMP) for elastic scattering, and its generalization to non-spherical shapes, the deformed optical model potential (DOMP) for inelastic scattering. These models are simple and phenomenological; their parameters are adjusted so as to reproduce empirical data. Nonetheless, there are certain, not always well-defined constraints to be imposed. The potential shapes and their parameter values must be reasonable and should vary in a smooth and systematic way with the masses of the colliding nuclei and theiry energy. Without these constraints, the potentials tell us very little, and they will be essentially useless for other purposes, such as in DWBA calculations. One way of satisfying these constraints, without going back to a much more fundamental theory, is through the use of folding models. Folding procedures allow one to incorporate many aspects of nuclear structure (although the nuclear size is one of the most important), as well as theoretical ideas about the effective interaction of two nucleons within nuclear matter. It also provides one with a means of linking information obtained from nuclear (hadronic) interactions with that from other sources, as well as correlating that from the use of different hadronic probes. Single-folded and doubling folding potentials are discussed, and applications in alpha and heavy ion scattering are discussed. (WHK)
