Limiting Temperatures in Multifragmentation

TL;DR

This paper investigates how isotopic effects influence the nuclear caloric curve in multifragmentation, providing insights into limiting temperatures and their theoretical predictions, with implications for understanding nuclear phase transitions.

Contribution

It offers new experimental data on isotopic effects in spectator fragmentation and discusses their implications for limiting temperatures in nuclear multifragmentation.

Findings

Isotopic effects influence the nuclear caloric curve

Results support Hartree-Fock model predictions

Chemical breakup temperatures relate to limiting temperatures

Abstract

The systematic data set on isotopic effects in spectator fragmentation collected recently at the GSI laboratory permits the investigation of the N/Z dependence of the nuclear caloric curve which is of interest in several respects. In particular, new light is shed on the proposed interpretation of chemical breakup temperatures as a manifestation of the limiting temperatures predicted by the Hartree-Fock model. The obtained results are discussed within the general context of temperature measurements in multifragmentation reactions.
