# Light charged clusters emitted in 32 MeV/nucleon 136,124Xe+124,112Sn reactions: chemical equilibrium, 3He and 6He production

## TL;DR

This study investigates nuclear particle production in Xe+Sn reactions at 32 MeV/nucleon, revealing N/Z equilibration in central collisions and neutron enrichment at mid-rapidity, with insights into cluster emission and isotope production.

## Contribution

It provides new experimental data on light charged cluster emission, N/Z equilibration, and neutron enrichment phenomena in intermediate-energy heavy-ion collisions.

## Key findings

- N/Z equilibration achieved in central collisions
- 3He exhibits pre-equilibrium emission characteristics
- 6He production indicates neutron enrichment at mid-rapidity

## Abstract

Nuclear particle production from peripheral to central events is presented. N/Z gradient between projectile and target is studied using the fact that two reactions have the same projectile+target N/Z and so the same neutron to proton ratio for the combined system. Inclusive data study in the forward part of the center of mass indicates that N/Z equilibration between the projectile-like and the target-like is achieved for central collisions. Particles are also produced from mid-rapidity region. 3He mean pre-equilibrium character is evidenced and 6He production at mid-rapidity implies a neutron enrichment phenomenon of the projectile target interacting zone.
