Fermi breakup and the Statistical Multifragmentation Model

TL;DR

This paper shows that a generalized Fermi breakup model, which considers excited state densities, closely resembles the statistical multifragmentation model used for describing nuclear reaction fragmentations.

Contribution

It introduces a generalized Fermi breakup model incorporating excited state densities and demonstrates its similarity to the microcanonical statistical multifragmentation model.

Findings

The generalized Fermi breakup model aligns closely with the statistical multifragmentation model.

Inclusion of excited state densities improves the model's accuracy.

The models are effectively equivalent in describing nuclear disintegration.

Abstract

We demonstrate the close similarity of a generalized Fermi breakup model, in which densities of excited states are taken into account, to the microcanonical statistical multifragmentation model used to describe the desintegration of highly excited fragments of nuclear reactions.
