# Microscopic calculations of weak decays in superheavy nuclei

## TL;DR

This paper performs microscopic calculations of beta+ decay and electron capture half-lives in superheavy nuclei using self-consistent Skyrme Hartree-Fock models, analyzing the effects of nuclear deformation and QEC energies.

## Contribution

It introduces a microscopic approach to calculate weak decay half-lives in superheavy nuclei, considering deformation and pairing effects, and compares them with alpha-decay data.

## Key findings

- Beta+ decay and electron capture half-lives are sensitive to nuclear deformation.
- Alpha decay remains the dominant decay mode in the studied superheavy nuclei.
- Half-life calculations depend significantly on the QEC energies.

## Abstract

Half-lives of beta+ decay and electron capture are studied in some selected superheavy nuclei produced in hot fusion reactions, namely, 290Fl, 293Mc, 294Lv, and 295Ts. The nuclear structure is described microscopically from deformed self-consistent Skyrme Hartree-Fock mean-field calculations that include pairing correlations. The sensitivity of the half-lives to deformation and to the QEC energies, which are still not determined experimentally, are studied. The results are compared with phenomenological alpha-decay half-lives, showing that the latter decay mode is dominant in this mass region.
