Neutron-triton elastic scattering

TL;DR

This paper applies advanced theoretical methods to study neutron-triton elastic scattering at low energies, using a non-local chiral interaction and comparing results with experimental data and other computational approaches.

Contribution

It introduces the first results using a non-local chiral interaction for neutron-triton scattering within the hyperspherical harmonics framework.

Findings

Good agreement with Faddeev-Yakubovsky calculations

Total and differential cross sections match experimental data

Including three-nucleon interactions affects scattering results

Abstract

The Kohn variational principle and the hyperspherical harmonics technique are applied to study n-3H elastic scattering at low energies. In this contribution the first results obtained using a non-local realistic interaction derived from the chiral perturbation theory are reported. They are found to be in good agreement with those obtained solving the Faddeev-Yakubovsky equations. The calculated total and differential cross sections are compared with the available experimental data. The effect of including a three-nucleon interaction is also discussed.
