Nuclear field theory of spin dealignment in strongly rotating nuclei and the vacuum polarization induced by pairing vibrations

Abstract

Processes where particles are dressed by pairing vibrations and where their average field is modified by the Fock contribution of the pairing force are found to give rise to dynamical dealignments of the single-particle motion in strongly rotating nuclei above the critical frequency. Typical values for an i132 orbital are 8 ̷ h̷, in qualitative agreement with the experimental findings.
