Charge exchange (p,n) reaction to isobaric analogue states of select nuclei

Using a modified version of Jacques Raynal’s program, DWBA98, we have analyzed cross-section data from a select set of charge exchange ( p , n ) reactions leading to isobaric analogue states of the target ground states. The Melbourne g -matrix model of the NN interaction has been used to specify both the relevant optical model potentials and the transition interactions. The formulation used defines transition amplitudes in terms of nucleon state occupancies in the ground states of the targets. Skyrme-Hartree-Fock and shell-model structures have been used for the input spectroscopic information. Targets of ^92 Zr, ^42,48 Ca, ^208 Pb, and ^6 He have been considered specifically.
