Analysis of total reaction cross sections for deuterons on 1 p -shell-nuclei

This study aims to analyze the differential cross sections (DCSs) of elastic scattering and total reaction cross sections (TRCSs) of the loosely-bound deuteron projectile impinging on 1p-shell nuclei, such as 9Be, 12C, and 16O, at incident energies ranging between 10.6 and 171 MeV using the continuum discretized coupled channel (CDCC) method. By fitting the experimental data for the DCSs and TRCSs, energy-dependent renormalization factors for the real and imaginary parts of the nucleon-nucleus optical-model potentials deduced from the studies proposed by Koning and Delaroche (KD02) and by Watson, Singh, and Segel (WSS), are obtained. It is found that with the WSS potential, which was obtained specifically for 1 p-shell nuclei, the CDCC calculations can simultaneously reproduce both the DCSs and the TRCSs. The results show that it is important to choose appropriate optical potentials to describe deuteron-induced reactions.
