Symmetrization of emitter size in violent “light” heavy ion collisions at intermediate energy

Vaporization and high multiplicity events, where the nuclear system is almost completely disassembled in light charged particles [Formula Presented] were analyzed for events with total charge detected [Formula Presented] in the [Formula Presented] reaction at 43 MeV/nucleon. Kinematic characteristics have been studied separately for [Formula Presented] and [Formula Presented] particles. When those are compared to simulations, noticeable differences in privileged emission direction have been found between [Formula Presented] particles and protons. For violent reactions, these differences could be explained by the apparent “symmetrization” of the reaction partners via the formation of a large necklike structure, and its subsequent breakup into many light ions.
