AN ACCURATE CALCULATION OF THE SUPERDEFORMED BANDS IN HG AND PB

The superdeformed (SD) rotational bands in the Hg and Pb isotopes are analyzed by means of the abc expression for rotational band: E(gamma)(I) = a[1 + cI(I + 1)] [square-root 1 + bI(I + 1) - 1], which was derived from the Bohr Hamiltonian. The agreement between the calculated and observed transition energies is remarkably good. The deviation of the calculated E s from the observed ones turns out to be \delta\ less-than-or-equal-to 0.5 keV (except for a few cases, 0.5 keV less-than-or-equal-to \delta\ less-than-or-equal-to 0.7 keV). Some transitions which have not been observed yet in these SD bands are predicted, which may be useful for experimental investigations.Physics, NuclearPhysics, Particles & FieldsSCI(E)0ARTICLE2161-1691
