摘要

Neutron-proton equilibration is a process which has been used to study the density dependence of the symmetry energy term in the nuclear equation-of-state. This study utilizes constrained molecular dynamics (CoMD) simulations of Zn-70 + Zn-70 with collision energies of 35 and 45 MeV/nucleon. An algorithm is used which searches through CoMD events and identifies the PLF* after it separates from the target and determines its lifetime, Delta t. It also determines the fragments that the PLF* breaks apart into and determines their angular alignment. This technique gives an opportunity to explore how the average alignment of dynamically produced fragments, (dyn), evolves with PLF* lifetime. An approximately linear relationship was determined with d (dyn)/d Delta t = 0.98 +/- 0.08 rad/zs and 1.06 +/- 0.09 rad/zs for the 35 and 45 MeV/nucleon, respectively, indicating a correlation with magnitude consistent with classically determined values which were used for prior experimental studies.
