A description of the dynamics and thermodynamics of vibration damping in axially deformed nuclei

The Quantal Brownian Motion (QBM) model of nuclear vibration damping is adapted to describe an axially deformed nucleus where a giant oscillatory mode becomes excited. Several simplifying assumptions are imposed in order to obtain an operative version of the QBM model. Within the restrictions posed...
