Formation of neutron-rich and superheavy elements in astrophysical objects

TL;DR

This paper models the formation of superheavy elements in astrophysical environments by calculating reaction and fusion cross-sections of neutron-rich nuclei using advanced theoretical frameworks.

Contribution

It introduces a detailed calculation of reaction and fusion cross-sections for neutron-rich heavy nuclei with exotic isotopes, predicting superheavy element formation in astrophysical r-process nucleosynthesis.

Findings

Neutron-rich Pb and U isotopes show significant fusion cross-sections.

Predictions indicate formation of superheavy elements via rapid neutron capture.

Theoretical models successfully estimate reaction probabilities in astrophysical conditions.

Abstract

We calculate the reaction and the fusion cross-sections of neutron-rich heavy nuclei taking light exotic isotopes as projectiles. Results of neutron-rich Pb and U isotopes are demonstrated as the representative targets and He, B as the projectiles. The Gluaber Model and the Coupled Channel Formalism are used to evaluate the reaction and the fusion cross-sections for the cases considered.Based on the analysis of these cross-sections, we predict the formation of heavy, superheavy and super-superheavy elements through rapid neutron/light nuclei capture r-process of the nucleosynthesis in astrophysical objects.
