Role of {\alpha}-cluster transfer in formation 20Ne+16O cross sections at backward angles

TL;DR

This paper investigates how alpha-cluster transfer influences the cross sections of 20Ne+16O elastic transfer at backward angles, using reanalyzed experimental data and DWBA calculations to understand the underlying nuclear structure effects.

Contribution

It introduces a detailed analysis of alpha-cluster transfer contributions in 20Ne+16O reactions using phenomenological and semi-microscopic potentials, extracting spectroscopic amplitudes.

Findings

Alpha-cluster transfer significantly increases cross sections at backward angles.

Theoretical models agree reasonably well with experimental data.

Spectroscopic amplitudes for 20Ne as 16O plus alpha are extracted.

Abstract

The experimental angular distributions for 20Ne+16O elastic transfer are reanalyzed using different forms of potential both phenomenological and semi-microscopic. The significant increase in cross sections at backward hemisphere due to the contribution of alphacluster transfer is investigated using the distorted wave Born approximation (DWBA) method. The spectroscopic amplitude (SA) for the configuration 20Ne as consisting of 16O (core) and an alpha-particle orbiting this core at the different concerned energies is extracted. The agreement between the experimental data and theoretical calculations using the two considered approaches is reasonably good.
