Effects of entrance channel on fusion probability in hot fusion reactions

TL;DR

This paper investigates how the entrance channel influences fusion probability in hot fusion reactions using the DNS model, showing that reactions with higher initial potential energy have enhanced fusion probabilities despite low mass asymmetry.

Contribution

It introduces a detailed analysis of fusion probabilities based on DNS potential energy, highlighting the impact of initial potential energy on fusion success.

Findings

Fusion probabilities are higher for reactions with high initial DNS potential energy.

Calculated results align well with experimental data.

Potential energy of the initial DNS significantly affects fusion probability.

Abstract

Within the framework of the dinuclear system (DNS) model, the fusion reactions leading to the compound nuclei 274Hs and 286Cn are investigated. The fusion probability as a function of DNS excitation energy is studied. The calculated results are in good agreement with the available experimental data. The obtained results show that the fusion probabilities are obviously enhanced for the reactions located at high place in potential energy surface, although these reactions may have small values of mass asymmetry. It is found that the enhancement is due to the large potential energy of the initial DNS.
