- Abstract
- Level density fluctuations are calculated within the generalized
interacting boson model proposed for even-even nuclei, in dependence on the
truncation parameter kappa . For the case kappa =2 corresponding to the
SU(3) dynamical symmetry of the interacting boson model the fluctuation
pattern is close to Poissonian. For cases kappa not=2, including the
anharmonic vibrator model for which kappa = infinity , a rapid transition to
the fluctuation pattern close to GOE is obtained. (40 References).
