Supernova {\beta}^- decay of nuclides 53Fe, 54Fe, 55Fe, and 56Fe in strongly screened plasma

TL;DR

This paper investigates how strong electron screening in plasma significantly enhances the beta decay rates of iron isotopes, with corrections leading to over tenfold increases compared to unscreened decay rates.

Contribution

It provides a detailed analysis of the impact of electron screening and Q-value correction on beta decay rates of iron isotopes in plasma environments.

Findings

Electron screening increases beta decay rates by about two orders of magnitude.

Q-value correction further amplifies decay rates by more than an order of magnitude.

Screened decay rates are significantly higher than unscreened rates.

Abstract

The electron screening strong effect on the electron energy and threshold energy of the beta decay reaction. in this paper, we study the $\beta^-$ decay rates of some iron isotopes. The electron screening beta decay rates increase by about two orders of magnitude. The strong screening beta decay rates due to Q-value correction are by more than one order of magnitude higher than those of without Q-value correction.
