A new inverse quasifission mechanism to produce neutron-rich transfermium nuclei

TL;DR

This paper introduces a novel inverse quasifission mechanism based on TDHF theory for producing neutron-rich transfermium nuclei through specific actinide collisions, highlighting the process's dynamics and influencing factors.

Contribution

It proposes a new inverse quasifission mechanism for synthesizing neutron-rich transfermium nuclei using time-dependent Hartree-Fock calculations.

Findings

Collision of the tip of one nucleus with the side of another facilitates nucleon transfer.

Nucleon evaporation and impact parameter significantly influence the process.

Collision time affects the nucleon flux and transfer efficiency.

Abstract

Based on time-dependent Hartree-Fock theory, a new inverse quasifission mechanism is proposed to produce neutron-rich transfermium nuclei, in collision of prolate deformed actinides. Calculations show that collision of the tip of one nucleus with the side of the other results in a nucleon flux toward the latter. The role of nucleon evaporation and impact parameter, as well as the collision time are discussed.
