Origins of intermediate velocity particle production in heavy ion reactions

Abstract

Investigation of intermediate-velocity particle production is performed on entrance channel mass asymmetric collisions of ${}^{58}\mathrm{Ni}+\mathrm{C}$ and ${}^{58}\mathrm{Ni}+\mathrm{Au}$ at 34.5 MeV/nucleon. Distinctions between prompt preequilibrium ejections, multiple neck ruptures, and an alternative phenomenon of delayed aligned asymmetric breakup are achieved using source reconstructed correlation observables and time-based cluster recognition in molecular dynamics simulations.
