Abstract

Dynamical quantum chaos criteria - a perturbed wave function entropy W (Ψ i and a fragmentation width K(pdbl k) of basis states were studied in two cases of nuclear rigid triaxial rotator models. The first model is characterized by deformation angle γ only, while the second model depends on both quadrupole deformation parameters (β,γ). The degree of chaoticity has been determined in the studies of the dependence of criteria W(Ψ i) and K(pdbl k) from nuclear spin values up to I ≤ 101 for model parameters γ and (β,γ) correspondingly. The transition from librational to rotational type energy spectra has been considered for both models as well.
