Quasi-elastic scattering and fusion with a modified Woods-Saxon potential

TL;DR

This paper investigates elastic and quasi-elastic scattering in nuclear reactions using a modified Woods-Saxon potential, successfully reproducing experimental data and providing insights into the underlying nuclear interaction mechanisms.

Contribution

It introduces a modified Woods-Saxon potential with fixed parameters for describing both scattering and fusion, incorporating nucleon transfer effects for improved accuracy.

Findings

The potential reproduces elastic scattering angle distributions at high energies.

Quasi-elastic cross sections are well matched with experimental data.

The model offers a unified description of scattering and fusion processes.

Abstract

The elastic and large-angle quasi-elastic scattering reactions were studied with the same nucleus-nucleus potential proposed for describing fusion reactions. The elastic scattering angle distributions of some reactions are reasonably well reproduced by the proposed Woods-Saxon potential with fixed parameters at energies much higher than the Coulomb barrier. With an empirical barrier distribution based on the modified Woods-Saxon potential and taking into account the influence of nucleons transfer, the calculated quasi-elastic scattering cross sections of a series of reactions are in good agreement with the experimental data.
