TL;DR

This paper introduces an evaporation prescription into time-dependent density functional calculations to better simulate heavy-ion collisions, especially for superheavy nuclei production, considering various reaction outcomes based on incident energy and impact parameter.

Contribution

The paper presents a novel evaporation prescription integrated into TDDFT calculations, enhancing the modeling of heavy-ion reactions and superheavy element synthesis.

Findings

Fusion, fusion-fission, and quasi-fission events are predicted.

Evaporation effects significantly influence reaction outcomes.

The method improves understanding of superheavy nuclei formation.

Abstract

Collisions between $^{248}$Cm and $^{48}$Ca are systematically calculated by time-dependent density functional calculations with evaporation prescription. Depending on the incident energy and impact parameter, fusion, fusion-fission, and quasi-fission events are expected to appear. In this paper, the evaporation prescription is introduced, which is expected to be rather important to heavy-ion reactions producing superheavy nuclei, where the heavier total mass can be related to the higher total excitation energy.
