Nonlocal interaction and collective excitation in deuteron breakup on ${}^{24}$Mg nucleus

TL;DR

This paper investigates deuteron breakup on magnesium-24 using advanced three-body scattering models, comparing local and nonlocal potentials, and finds that nonlocality effects are less significant than in similar inelastic scattering processes.

Contribution

It extends three-body scattering equations to include nuclear excitation and compares local and nonlocal optical potentials in deuteron breakup analysis.

Findings

Nonlocality effects are less pronounced than in inelastic scattering.

Nonlocality manifests differently in elastic and inelastic breakup cross sections.

Predictions highlight differences between local and nonlocal potential models.

Abstract

Deuteron breakup in collision with a ${}^{24}\mathrm{Mg}$ nucleus is studied using rigorous three-body scattering equations, extended to include also the excitation of the nucleus. Predictions based on local and nonlocal nucleon-nucleus optical potentials with rotational quadrupole deformation enabling the excitation of the ${}^{24}\mathrm{Mg}(2^+)$ state are compared. The nonlocality effect is less pronounced than in the deuteron inelastic scattering ${}^{24}\mathrm{Mg}(d,d')$ at the same energies, and manifests itself quite differently for semi-inclusive differential cross sections of elastic and inelastic breakup.
