Chiral geometry and rotational structure for Cs in the projected shell model
The projected shell model with configuration mixing for nuclear chirality is
developed and applied to the observed rotational bands in the chiral nucleus
Cs. For the chiral bands, the energy spectra and electromagnetic
transition probabilities are well reproduced. The chiral geometry illustrated
in the and the is confirmed to be stable against the
configuration mixing. The other rotational bands are also described in the same
framework
Low-lying states in even Gd isotopes studied with five-dimensional collective Hamiltonian based on covariant density functional theory
Five-dimensional collective Hamiltonian based on the covariant density
functional theory has been applied to study the the low-lying states of
even-even Gd isotopes. The shape evolution from Gd to
Gd is presented. The experimental energy spectra and intraband
transition probabilities for the Gd isotopes are reproduced by the
present calculations. The relative ratios in present calculations are
also compared with the available interacting boson model results and
experimental data. It is found that the occupations of neutron
orbital result in the well-deformed prolate shape, and are essential for Gd
isotopes.Comment: 11pages, 10figure
