SOME ASPECTS OF STUDIES OF INTERACTIONS BETWEEN TWO LIGHT NUCLEAR SYSTEMS

Abstract

Publisher Summary This chapter presents some aspects of studies of interactions between two light nuclear systems. Few-nucleon scattering data have been useful in deriving interactions between light nuclear systems. Formulations have been made to construct unique interaction potentials from the inverse scattering theory, given the phase shifts at all energies. The inverse problem has been thoroughly studied for local potentials and also investigated for separable ones. The usual difficulty with potential construction from the inverse theory, apart from the computational one is that the experimental phase shifts are mostly given in rather limited energy interval and that too with some inaccuracies and sometimes inconsistencies. This may lead to unphysical behavior in the constructed potentials and as a result, analytical expressions, which are desirable in many cases, cannot be fitted to these potentials. An important approach in understanding the interactions between two light nuclear systems has been the calculation from first principles.
