Role of α-Cluster Transfer in the Formation of 20Ne + 16O Cross-Sections at Backward Angles

Abstract

The experimental angular distributions for 20 Ne+ 16 O 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 α-cluster transfer is investigated using the distorted wave Born approximation (DWBA) method. The spectroscopic amplitude (SA) for the configuration 20 Ne→ 16 O+α at the different concerned energies is extracted. The agreement between the experimental data and theoretical calculations using the two considered approaches is reasonably good.
