Prediction of stable superheavy nuclei

TL;DR

This paper predicts the most stable superheavy nuclei by analyzing decay modes, providing potential targets for laboratory synthesis and supporting the island of stability hypothesis.

Contribution

It identifies twelve superheavy nuclei with predicted long half-lives, expanding understanding of nuclear stability in the superheavy element region.

Findings

Nine nuclei stable via fission with long half-lives

Three nuclei stable via alpha decay with extensive half-lives

Supports the existence of an island of stability for superheavy elements

Abstract

We have investigated most stable superheavy nuclei by studying the decay properties such as alpha decay, cluster decay and spontaneous fission. We have investigated nine stable nuclei in the island of stability which can be detected through fission are 318123(10.5ms), 319123(4.68{\mu}s), 317124(1.74x104 y), 318124(2.70x101 y), 319124(2.83x10-2 y), 320124(1.91x10-5 y), 319125(2.46x109 y), 320125(3.81x106 y) and 321125(3.99x103 y). Present work also investigates three stable superheavy nuclei which can be detected through alpha decay which are 318125(1.03x1012 y), 319126(5.77x1011 y) and 320126(3.99x1010 y). These nuclei will become most stable nuclei if they synthesized in the laboratory. The identified twelve stable nuclei is the evidence for the hypothesis of island of stability
