Macroscopic manifestations of rotating triaxial superfluid nuclei

Abstract

Recently, Allmond and Wood [Phys. Lett. B 767, 226 (2017)] were able to extract the three moments of inertia Ik of a dozen of superfluid triaxial nuclei from experimental data. The observed dependence of the Ik 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.
