Optical model potential of deuteron with $1p$-shell nuclei

TL;DR

This paper develops a new set of global optical potential parameters, DA1p, for deuterons interacting with 1p-shell nuclei, improving the accuracy of elastic scattering predictions across a range of nuclei and energies.

Contribution

The paper introduces DA1p, a novel global optical potential parameter set specifically optimized for deuteron interactions with 1p-shell nuclei, based on extensive experimental data fitting.

Findings

DA1p provides better elastic scattering predictions than previous potentials.

The model accurately reproduces experimental data for various 1p-shell nuclei.

It also fits data for radiative nuclei like 9Li, 10Be, 14C, and 14O.

Abstract

A set of global optical potential parameters, DA1p, for deuterons with the $1p$-shell nuclei is obtained by simultaneously fitting 67 sets of experimental data of deuteron elastic scattering from \nuc{6}{Li}, \nuc{9}{Be}, \nuc{10}{B}, \nuc{11}{B}, \nuc{12}{C}, \nuc{13}{C}, \nuc{14}{N}, \nuc{16}{O} and \nuc{18}{O} with incident energies between 5.25 and 170 MeV. DA1p improves the description of the deuteron elastic scattering from the $1p$-shell nuclei with respect to the existing systematic deuteron potentials and can give satisfactory reproduction to the experimental data with radiative nuclei such as \nuc{9}{Li}, \nuc{10}{Be}, \nuc{14}{C} and \nuc{14}{O}.
