The rotational spectroscopic properties of reflection-asymmetric nuclei investigated by the
reflection-asymmetric axial or triaxial particle rotor model are briefly reviewed. The status of …

Background: Many nuclear-structure features have been observed in actinides in recent
decades. In particular, the octupole degree of freedom has been discussed lately after the …

The recently updated parity doublet structures in Th 223 are investigated by using the
reflection-asymmetric triaxial particle rotor model. The calculated results well reproduce the …

We report the results of a study of rotational bands in Ra 219 via the Pb 208 (C 14, 3 n)
reaction to look for evidence that this nucleus is statically octupole deformed. We add 19 γ …

The level structure of the transitional nucleus Ra 217 has been extended with the addition of
around 20 new transitions. The discrepancies between the placements of several transitions …

The level structure of the transitional nucleus $\mathrm {^{217} Ra} $ has been extended
with the addition of around 20 new transitions. The discrepancies between the placements …

Three new isomers have been identified in the transitional odd-odd Fr 216 nucleus. The
properties of the (11+) isomer with T 1/2= 9.6 (14) ns are compared with those of the similar …

We report on cranked Skyrme-HFB calculations of rotational bands of the octupole-deformed
nucleus $^{222} $ Th. A sudden change in configuration is observed, with the shape of the …

Excited metastable states which face an inhibition in their decay to low-lying states are
termed isomers [1, 2]. Although there is no stringent rule on the minimum half-life for a state …

In this chapter, the microscopic origin of nuclear deformation is studied in terms of mean field
and shell model. The observation of rotational spectra and electromagnetic moments are …
