Radiative nucleon capture - a dual approach

Abstract

Abstract. The nucleon radiative capture reactions represent a great interest for possible new ways of production of therapeutic and diagnostic isotopes and also for their deep insight into the details of nuclear reaction process itself. The high-energy gammas originating from the reactions of nucleon radiative capture at incident energies close to or above 10 MeV can be described by either the semi-direct-direct model or within the pre-equilibrium approach. The detailed view on the origin of the optical model potential indicates the origin of its imaginary part. Both approaches are compared together and also to the data.

“…On the other hand, it gives also a good and reliable description at energies as low as about 5 MeV [16,17]. The γ emission rates can be expressed as [6,7] …”
