Critical temperature for the nuclear liquid-gas phase transition (from multifragmentation and fission)

TL;DR

This paper estimates the critical temperature for the nuclear liquid-gas phase transition using multifragmentation and fission data, concluding it exceeds 16 MeV, through statistical modeling and probability comparison.

Contribution

It provides a combined analysis of multifragmentation and fission data to estimate the critical temperature for nuclear phase transition, a novel approach in this context.

Findings

Critical temperature exceeds 16 MeV.

Consistent results from multifragmentation and fission analyses.

Supports the existence of a high-temperature nuclear liquid-gas phase transition.

Abstract

Critical temperature Tc for the nuclear liquid-gas phase transition is stimated both from the multifragmentation and fission data. In the first case,the critical temperature is obtained by analysis of the IMF yields in p(8.1 GeV)+Au collisions within the statistical model of multifragmentation (SMM). In the second case, the experimental fission probability for excited 188Os is compared with the calculated one with Tc as a free parameter. It is concluded for both cases that the critical temperature is higher than 16 MeV.
