Abstract
The isovector parts of the effective nucleon-nucleon interaction are studied by examination of the reaction (p,n) at intermediate energies near zero momentum transfer with use of recently developed G-matrix and free–t-matrix interactions. The spin-independent coupling () exhibits a strong energy and density dependence which, in the case of the G matrix based on the Bonn potential, significantly improves the agreement between calculated values of ‖/ at q=0 and those recently extracted from the reaction (p,n).
