Nuclear Matter Incompressibility Effect on the Cross Section of Fusion Reactions with a weakly bound projectile

TL;DR

This paper investigates how nuclear matter incompressibility influences fusion reaction cross sections involving weakly bound projectiles, using a modified double-folding model to improve agreement with experimental data.

Contribution

It introduces a modified potential incorporating nuclear matter incompressibility effects into fusion reaction calculations with weakly bound projectiles.

Findings

Inclusion of incompressibility effects improves cross section predictions near the Coulomb barrier.

The model better matches experimental suppression parameters.

Results are consistent across multiple target nuclei.

Abstract

Fusion reactions with a weakly bound projectile are studied using the double-folding model along with a repulsive interaction modifying term. Using this modified potential, including nuclear matter incompressibility effects, the fusion reaction cross sections and suppression parameters are calculated for 9Be +209Bi,208Pb,29Si and 27Al reactions. The results show that applying these effects at energies near the Coulomb barrier improves the agreement between the calculated and experimental cross sections, and modifies the mean values of the suppression parameter.
