It introduces a comprehensive comparison of global and folding deuteron optical potentials, highlighting the optimal Skyrme force parameters for microscopic nucleon potentials.

Findings

SKa and SKb are the best Skyrme parameters for folding deuteron optical potentials.

The study provides detailed $ ext{chi}^2$ analyses for 11 potential types.

Folding potentials with SKa and SKb outperform others in reproducing experimental data.

Abstract

For 52 target nuclei with deuteron as projectile, we calculate the reaction cross sections and elastic scattering angular distributions, as well as the $\chi^2$ values for 11 kinds of deuteron optical model potentials: our global deuteron optical potentials and 10 folding optical potentials calculated with 2 phenomenological global nucleon optical potentials given by Koning \textit{et al}(KD) and by Varner\textit{et al}(CH89), and 8 microscopic nucleon optical potentials with the generalized Skyrme force parameters(GS1-6) and modified Skyrme force parameters(SKa, SKb). We find that for constructing the folding deuteron optical potential, both SKa and SKb are the best Skyrme force parameters of the microscopic nucleon optical potential proposed by Q. Shen \textit{et al}.
