Anti-cluster Decay and Anti-alpha Decay of Antimatter nuclei

TL;DR

This paper predicts that antimatter nuclei will exhibit anti-alpha decay with similar properties to matter nuclei, extending nuclear decay concepts into antimatter and providing specific decay data for antimatter isotopes.

Contribution

It introduces the concept that antimatter nuclei undergo anti-alpha decay with identical Q-values and half-lives as their matter counterparts, extending nuclear decay theories.

Findings

Anti-alpha decay from antimatter nuclei has the same Q-value and half-life as matter nuclei.

The paper provides decay data for 27 cluster radioactivities and alpha decay.

The lightest anti-alpha emitter, $^8ar{Be}$, has an extremely short half-life.

Abstract

A broad extension of periodic system into the sector of antimatter could be possible sometimes in a remote future. We expect that anti-alpha spontaneous emission from an antimatter nucleus will have the same Q-value and half-life as alpha emission from the corresponding mirror nucleus. This is the consequence of the invariance of binding energy as well as of the surface and Coulomb energy when passing from matter to antimatter nuclei with the the same mass number and the same atomic number. The Q-values and half-lives of all measured up to now 27 cluster radioactivities are given together with Q-values and half-lives of the most important competitor --- $\alpha$ decay. The lightest anti-alpha emitter, $^8\bar{Be}$, will have a very short half-life of about $81.9\cdot 10^{-18}$ s.
