Freeze-out configuration properties in the 197Au + 197Au reaction at 23 AMeV

TL;DR

This study analyzes gold-gold collision data at 23 AMeV to identify signatures of exotic nuclear shapes like toroids, comparing experimental results with models to suggest possible formation of flat or toroidal nuclear systems.

Contribution

Introduces a new event selection criterion called 'the efficiency factor' and compares experimental data with models to explore exotic nuclear configurations.

Findings

Evidence suggesting formation of toroidal nuclear systems

Validation of the 'efficiency factor' as an event selection tool

Comparison indicates potential existence of flat/toroidal configurations

Abstract

Data from the experiment on the 197Au + 197Au reaction at 23 AMeV are analyzed with an aim to find signatures of exotic nuclear configurations such as toroid-shaped objects. The experimental data are compared with predictions of the ETNA code dedicated to look for such configurations and with the QMD model. A novel criterion of selecting events possibly resulting from the formation of exotic freeze-out configurations, "the efficiency factor", is tested. Comparison between experimental data and model predictions may indicate for the formation of flat/toroidal nuclear systems.
