Rotational bands in 108,110,112Ru have been investigated by means of γ – γ – γ and γ – γ ( θ ) coincidences of prompt γ rays emitted in the spontaneous fission of 252Cf. The positive parity bands are described by different versions of IB

Using time-dependent Hartree-Fock, we induce isoscalar and isovector monopole vibrations and follow the subsequent vibrations of both the same and opposite isospin nature in the N ≠ Z nucleus 132Sn. By suitable scaling of the proton and neutron par

We study isovector giant monopole resonances in spherical nuclei using the time-dependent Hartree–Fock method with different Skyrme forces. The aim of the investigation is to study how, for example, mass number and neutron excess influence the isov

Structures have been identified built upon the Kπ = 43/2(−) and Kπ = 43/2+ isomeric states in 183Os. Although these sequences appear quite irregular, their properties can be understood if the angular momentum is built up, to a large degree, from

We investigate the shape mixing in 68 Se using the adiabatic self-consistent collective method. This nucleus 68 Se is known to show oblate-prolate shape coexistence at low angular momentum. We calculate the collective path between the oblate and prol

We investigate shape coexistence in a rotating nucleus. We concentrate on the case of 72 Kr which exhibits an interesting interplay between prolate and oblate shaped states as a function of angular momentum. The calculation uses the local harmonic ve

The contribution of quantum shape fluctuations to inertial properties of rotating nuclei has been analyzed for QQ-nuclear interaction using the random phase approximation (RPA). The different recipes to treat the cranking mean field plus RPA problem

Using the Hamiltonian that consists of the separable quadrupole + pairing forces and the cranking term, we analyze the correlations associated with shape, orientation, and particle-number fluctuations in rotating nuclei. Quantum fluctuations around m

The spectroscopic quadrupole moment of the high-spin, high- K five-quasiparticle isomer (K(pi) = 35/2(-), T(1/2) = 750(80) ns, E(i) = 3349 keV) in (179)W has been determined using the level mixing spectroscopy method. A value Q(s) = 4.00(+0.83-1.06)e
