New developments in fission studies within the time-dependent density functional theory framework

TL;DR

This paper advances the microscopic understanding of nuclear fission by analyzing a broad set of observables using time-dependent density functional theory, including fragment properties, emitted neutrons, energy sharing, and entanglement.

Contribution

It significantly extends the microscopic description of fission by incorporating a wider range of observables and using two independent energy density functionals.

Findings

Detailed fragment neutron and proton numbers and spins obtained.

Insights into neutron emission and energy sharing mechanisms.

Quantitative analysis of fragment kinetic energy and entanglement entropy.

Abstract

We have extended significantly the microscopic description of the fission process by examining a larger set of observables. We extract neutron and proton numbers of fission fragments, their spins and fission fragment relative orbital angular momentum and their correlations, investigate neutrons emitted at or shortly after scission, excitation energy sharing mechanism, total kinetic energy of fission fragments, and the entanglement entropy. I will present a short overview of our simulations obtained with two independent nuclear energy density functionals.
