The Coupled-Channel Born-Approximatiom Calculation of the Reaction ¹⁰⁰Mo(t, p)¹⁰²Mo

Abstract

The transitions to the ground state and the first 2⁺ state in the reaction ¹⁰⁰Mo(t, p)¹⁰²Mo were calculated in the coupled-channel Bornapproximation (CCBA). The calculations of the microscopic spherical phonon model and the deformed medel were carried out for the structure of the nuclei ¹⁰⁰Mo and ¹⁰²Mo. The inelastic process was treated macroscopically for both models. The results of the two models were compared. Concerning the ratio of the cross section of the ground state to that of the first 2⁺ state, the spherical phonon model is preferable to the deformed model. In order to see the change of angular distribution and magnitude of the direct and indirect transitions to the first 2⁺ state due to the variation of the coupling parameter and to examine the validity of the DWBA treatment of the inelastic process numerically, model calculations were performed with the form factor obtained by assuming two-neutron (g_7⁄2)² configuration in the Woods-Saxon well for the states of ¹⁰²Mo.
