摘要：

The collective moment of inertia is derived analytically within the cranking model in the adiabatic mean-field approximation at finite temperature. Using the nonperturbative periodic-orbit theory the semiclassical shell-structure components of the collective moment of inertia are obtained for any potential well. Their relation to the free-energy shell corrections are found semiclassically as being given through the shell-structure components of the rigid-body moment of inertial of the statistically equilibrium rotation in terms of short periodic orbits. Shell effects in the moment of inertial disappear exponentially with increasing agreement between semiclassical and quantum shell-structure components of the free energy and the moment of inertial for several critical bifurcation deformations and several temperatures.
