New Approach for Evaluating Incomplete and Complete Fusion Cross Sections with Continuum-Discretized Coupled-Channels Method

TL;DR

This paper introduces a novel method using the Continuum-Discretized Coupled-Channels approach to separately evaluate incomplete and complete fusion cross sections, explicitly considering deuteron breakup effects.

Contribution

The study presents a new technique for fusion cross section analysis that improves upon existing models by explicitly accounting for breakup effects and comparing results with the Glauber model.

Findings

Incomplete fusion cross sections have similar energy dependence in both models.

Complete fusion cross sections differ significantly between the models.

Previous prescriptions underestimate incomplete fusion cross sections compared to experimental data.

Abstract

We propose a new method for evaluating incomplete and complete fusion cross sections separately using the Continuum-Discretized Coupled-Channels method. This method is applied to analysis of the deuteron induced reaction on a 7Li target up to 50 MeV of the deuteron incident energy. Effects of deuteron breakup on this reaction are explicitly taken into account. Results of the method are compared with those of the Glauber model, and the difference between the two is discussed. It is found that the energy dependence of the incomplete fusion cross sections obtained by the present calculation is almost the same as that obtained by the Glauber model, while for the complete fusion cross section, the two models give markedly different energy dependence. We show also that a prescription for evaluating incomplete fusion cross sections proposed in a previous study gives much smaller result than an experimental value.
