# Macroscopic manifestations of rotating triaxial superfluid nuclei

## TL;DR

This paper demonstrates that the moments of inertia of superfluid triaxial nuclei can be effectively explained using a semiclassical cranked Hartree-Fock-Bogoliubov model combining rigid and irrotational flow components, aligning well with experimental data.

## Contribution

The study introduces a semiclassical model that accurately reproduces experimental moments of inertia in superfluid triaxial nuclei, providing new insights into their macroscopic behavior.

## Key findings

- Model reproduces experimental moments of inertia accurately.
- Superposition of rigid and irrotational flows explains observed data.
- Smooth dependence of moments on deformation parameters is captured.

## Abstract

Recently, Allmond and Wood [Phys. Lett. B 767, 226 (2017)] were able to extract the three moments of inertia $I_k$ of a dozen of superfluid triaxial nuclei from experimental data. The observed dependence of the $I_k$ on the deformation parameters is rather smooth. Here we show that these moments of inertia can be surprisingly well explained by a semiclassical cranked Hartree-Fock-Bogoliubov (HFB) calculation in which the velocity field is a simple superposition of rigid and irrotational flows.
