STUDY OF THE SUPERDEFORMED NUCLEI IN A=190 REGION WITH THE CRANKING BOHR-MOTTELSON HAMILTONIAN

摘要

Transition energies of 55 superdeformed bands in 20 nuclei of the A = 190 region are studied with formulae derived from the Cranking Bohr-Mottelson Hamiltonian and the level spins ate determined. Mass parameter B-1 and rigidity parameter C-0 are obtained from the fitting parameters A and <(h)over bar omega'>. The B-1 and C-0 values show clear odd-even effects. Deviations from the simple model are discussed. (C) 1997 Elsevier Science B.V. [References: 36]
