TL;DR
This paper uses microscopic TDHF theory to study quasifission, a key process limiting superheavy element formation, with new insights into the $^{48}$Ca+$^{249}$Bk system.
Contribution
The study applies fully microscopic TDHF simulations to analyze quasifission dynamics in specific heavy-ion collisions, providing novel detailed results.
Findings
Quasifission involves longer nuclear contact-times than deep-inelastic reactions.
Significant mass and charge transfer occurs during quasifission.
Results offer new understanding of the $^{48}$Ca+$^{249}$Bk system dynamics.
Abstract
Quasifission is the primary reaction mechanism that limits the formation of superheavy nuclei and consequently an important ingredient for choosing the best target-projectile combinations for the heavy element searches. Quasifission is characterized by nuclear contact-times that are much longer than those found in deep-inelastic reactions, resulting in a substantial mass and charge transfer. In this manuscript we employ the fully microscopic time-dependent Hartree-Fock (TDHF) theory to study quasifission. New results are presented for the Ca+Bk system.
