Mass dispersions from giant dipole resonances using the Balian-Veneroni variational approach

TL;DR

This paper applies the Balian-Veneroni variational approach with a 3D TDHF code to study mass dispersions in giant dipole resonances, revealing larger fluctuations than standard TDHF in S-32 and Sn-132.

Contribution

It introduces a novel application of the Balian-Veneroni approach with realistic interactions to better quantify mass dispersions in nuclear giant dipole resonances.

Findings

Fluctuations are larger than standard TDHF results.

Mass dispersions are quantitatively improved.

Decays through particle emission in specific isotopes.

Abstract

The Balian-Veneroni variational approach has been implemented using a 3-dimensional time-dependent Hartree-Fock (TDHF) code with realistic Skyrme interactions and used to investigate the mass dispersions from giant dipole resonances in S-32 and Sn-132 decaying through particle emission. The fluctuations obtained are shown to be quantitatively larger than the standard TDHF results.
