Electromagnetic production of positron and electron in collisions of heavy nuclei

TL;DR

This paper studies how slow heavy nuclei collisions produce electron-positron pairs through electromagnetic interactions, mainly resulting in positron emission with the electron captured by the nucleus.

Contribution

It presents a detailed analysis of positron-electron pair production in slow heavy nuclei collisions, highlighting the dominance of positron emission and electron capture.

Findings

Positron emission dominates the pair production process.

Electrons are primarily captured by the nuclei during collisions.

The process is driven by electromagnetic interactions in slow heavy nuclei collisions.

Abstract

We consider the electromagnetic production of positron and electron in collisions of slow heavy nuclei. This process is dominated by emission of positron, with the electron captured by nucleus.
