Level density fluctuations in the generalized interacting boson model

  • Published:
Zeitschrift für Physik A Hadrons and nuclei

Abstract

Level density fluctuations are calculated within the generalized interacting boson model proposed for even-even nuclei, in dependence on the truncation parameter k. For the case ϰ=2 corresponding to the SU(3) dynamical symmetry of the interacting boson model the fluctuation pattern is close to Poissonian. For cases ϰ≠2, including the anharmonic vibrator model for which ϰ=∞, a rapid transition to the fluctuation pattern close to GOE is obtained.
