A modified proximity approach in the fusion of heavy-ions

TL;DR

This paper presents a modified proximity potential model for heavy-ion fusion that improves data fit by adjusting key parameters, reducing previous overestimations and aligning closely with experimental results.

Contribution

The authors introduce a modified proximity potential with optimized parameters, enhancing the accuracy of fusion barrier predictions over the original 1977 model.

Findings

Reduced overestimation of data from 4% to a lower margin

Enhanced agreement with experimental fusion data

Improved predictive capability of the proximity potential model

Abstract

By using a suitable set of the surface energy coefficient, nuclear radius, and universal function, the original proximity potential 1977 is modified. The overestimate of the data by 4 % reported in the literature is significantly reduced. Our modified proximity potential reproduces the experimental data nicely compared to its older versions.
