The lead region is considered as a paradigm of the shape coexistence phenomenon and several decades of experimental effort have supported this believe. In particular, long chains of the Pb, Hg, Pt and Po isotopes have been measured and a rich experimental body of data concerning excitation energies, electromagnetic transition rates, radii, magnetic g-factors, alpha-hindrance factors and...

I discuss calculations of states with angular momentum zero in nuclei with equal numbers of neutrons and protons and either four or eight nucleons or nucleon holes in the 1f7/2 or 1g9/2 shell with effective interactions from the literature. Consistently and fairly independently of the interaction, the ground states have by about 75% seniority zero in Flowers’s classification of states in a...

Properties of the isoscalar dipole toroidal resonance (TR) in spherical and deformed nuclei are discussed using our recent results obtained within the self-consistent random phase approximation with Skyrme forces [1-4]. The TR strength functions, transition densities and velocity fields are inspected. The resonance is compared to other exotic isoscalar dipole modes (compression and pygmy)...

Recent experimental discoveries have revealed that the neutron effective single particle evolution above 78Ni shows peculiar behaviours. The neutron monopole drifts towards 78Ni remain an open and urgent question and the light odd-neutron N=51 nuclei (towards 78Ni) constitute the most interesting cases to study this evolution. Low-lying states in N=51 isotones may naturally be understood in...

The theoretical B(E2) ratios have been calculated on DF, DR and Krutov models. A simple method based on the work of Arima and Iachello is used to calculate the reduced transition probabilities within SU(3) limit of IBA-I framework. The reduced E2 transition probability ratios of 2-gamma/ 2-ground to 2-gamma/ 0-ground from second excited states of rare-earths and actinide even–even nuclei...

We derive a microscopic version of the successful phenomenological hydrodynamic model of Bohr-Davydov-Faessler-Greiner for collective rotation-vibration motion of an axially symmetric deformed nucleus. The derivation is not limited to small oscillation amplitude. The nuclear Schrodinger equation is canonically transformed to collective co-ordinates, which is then linearized using a...

The possible occurrence of superheavy nuclei(SHN) in nature, neutron stars, pallasite meteorites validated the theoretical predictions about the occurrence of SHN in nature. Very recently, Zagrebaev et al. estimated the possibility of production of SHN in the astrophysical r process. Ohnishi and Okamoto has studied the nuclear structure properties of neutron magic numbers 184, 228 and 308...
