Intermediate Mass Fragment Emission in ${^{32}}$S +${^{51}}$V, ${^{109}}$Ag, and ${^{238}}$U Collisions at E~=~31.6~MeV~A

TL;DR

This study investigates intermediate mass fragment emission in sulfur-vanadium, silver, and uranium collisions at 31.6 MeV per nucleon, analyzing charge distributions and isotope ratios with various models.

Contribution

It compares different theoretical models, including coalescence and statistical multifragmentation, to experimental data on fragment emission in heavy-ion collisions.

Findings

Charge distributions were obtained successfully.

Coalescence and statistical models reproduced data well.

Quantum molecular dynamics models were less successful.

Abstract

Intermediate mass fragment emission for reactions of $^{32}\text{S} +\,^{51}\text{V},\,^{109}$Ag, and $^{238}\text{U}$ has been studied. Double differential cross sections were analysed in terms of the generalised moving source model yielding charge distributions. Isotope ratios show strong fragment mass dependencies. The data were successfully reproduced by the coalescence model as well as by statistical multifragmentation model calculations. Quantum molecular dynamics model calculations were not so successful.
