Isospin dependent effective interaction in nucleon-nucleus scattering
Taksu Cheon, Kazuo Takayanagi
Abstract
The isospin-dependent component of the effective nucleon-nucleon interaction that causes the ΔT=1 (p, p') and (p, n) reactions off nuclei is studied. It is shown that the corrections to the impulse approximation comes from the g-matrix type correction and the rearrangement term. They are numerically estimated with the isospin-asymmetric nuclear-matter reaction matrix approach. The analysis of the isobaric analog transitions 42Ca(p,n)42Sc and 48Ca(p,n)48Sc are presented.
