Coupled-channels description of the 40Ca+58,64Ni transfer and fusion reactions

TL;DR

This paper analyzes transfer and fusion reactions in calcium-nickel systems using coupled-channels methods, highlighting limitations in current models to simultaneously match transfer probabilities and fusion enhancements.

Contribution

It demonstrates that a simple coupled-channels approach cannot fully explain experimental transfer and fusion data in these systems.

Findings

Coupled-channels approach struggles to reproduce transfer probabilities.

Fusion cross section enhancement is not captured by simple models.

Transfer and fusion data require more complex modeling.

Abstract

Preliminary experimental data for nucleon transfer reactions of the 40Ca+58Ni and 40Ca+64Ni systems are analyzed with the coupled- channels approach. It is shown that a simple treatment for the transfer in the coupled-channels method cannot reproduce simultaneously the transfer probabilities and the sub-barrier enhancement of fusion cross sections.
