Enhanced production of $^{8}$Be nuclei in relativistic nuclei fragmentation

TL;DR

This paper reports on measurements of relativistic nuclei fragmentation, highlighting the production of unstable $^{8}$Be nuclei and their contribution to alpha particle multiplicities in nuclear track emulsion experiments.

Contribution

It presents new experimental data on $^{8}$Be production in relativistic nuclear fragmentation, including measurements with $^{84}$Kr nuclei at 950 MeV per nucleon.

Findings

$^{8}$Be nuclei contribute significantly to alpha particle multiplicities.

Fragmentation patterns vary among different relativistic nuclei.

Enhanced $^{8}$Be production observed in recent measurements.

Abstract

This article is dedicated to the results of early measuring fragmentation of relativistic $^{16}$O, $^{22}$Ne, $^{28}$Si, and $^{197}$Au nuclei in a nuclear track emulsion. It has been found that there is a contribution of the unstable $^8$Be nucleus decays to $\alpha$-particle multiplicities. These renewed measurements of nuclear track emulsion exposed to $^{84}$Kr nuclei at the energy of 950 MeV per nucleon have been analyzed and given below.
