Investigating the time dependence of neutron-proton equilibration using molecular dynamics simulations

NUCLEAR REACTIONS ⁷⁰Zn(⁷⁰Zn, X), E=35 MeV/nucleon; analyzed experimental yields from 2017RO09 (Phys. Rev. C 95, 044604) and and 2017JE01 (Phys. Rev. Lett. 118, 062501); deduced yields charge distributions and mass distribution for heavy and light fragments, fragments velocity distribution, angular distributions, neutron-to-proton ratio in the fragments. Simulations using Constrained Molecular Dynamics (COMD) and Antisymmetrized Molecular Dynamics (AMD) codes, which simulate the collision dynamics by solving time-dependent wave functions. GEMINI code used for de-excitation process.
