Cluster radioactivity in $^{114}$Ba in the HFB theory

TL;DR

This paper models the cluster radioactivity of $^{114}$Ba as a spontaneous fission process with a large mass asymmetry, revealing a new fission pathway with a long half-life using the HFB theoretical framework.

Contribution

It introduces a new fission valley with large octupole deformation in $^{114}$Ba within the self-consistent HFB theory, advancing understanding of cluster radioactivity mechanisms.

Findings

Identification of a new fission valley with large octupole deformation.

Prediction of $^{16}$O emission with a very long half-life.

Correlation of fragment mass asymmetry with expected cluster radioactivity.

Abstract

Cluster radioactivity in $^{114}$Ba is described as a spontaneous fission with a large mass asymmetry within the self-consistent HFB theory. A new fission valley with large octupole deformation is found in the potential energy surface. The fragment mass asymmetry of this fission mode corresponds to the expected one in cluster radioactivity with the emission of $^{16}$O predicted with a very long half-life.
