A nucleation model analysis of neck emission yields in 124Sn+112,124Sn reactions at 26 MeV/nucleon

TL;DR

This paper applies a nucleation-based statistical model to analyze neck emission yields in Sn+Sn collisions at 26 MeV/nucleon, successfully reproducing isotope yields and comparing equilibrium constants with fission data.

Contribution

It extends a nucleation model previously used for fission to analyze neck emission in heavy-ion collisions, providing new insights into the reaction mechanisms.

Findings

Model reproduces lithium to silicon isotope yields

Realistic time and temperature parameters obtained

Comparison with fission equilibrium constants shows consistency

Abstract

A recent analysis of experimental ternary fission fragment yields using a nucleation moderated statistical equilibrium model reproduced observed yields with fairly good accuracy. In the present work, the same approach is applied to neck emission in peripheral and mid-peripheral 124Sn+112,124Sn collisions at 26A MeV. The model can reasonably reproduce the yields of lithium to silicon isotopes with realistic time and temperature values. A comparison is made between equilibrium constants derived from the present data and those previously obtained for ternary fission of 242Pu.
