Axial shape asymmetry and high-spin states in nuclei with Z=100 suggested by the projected total energy surface approach

NUCLEAR STRUCTURE 246,248,250,252,254,256Fm; calculated levels, J, π, yrast bands, moment of inertia of yrast bands as function of rotational frequency, β2 and γ deformation parameters, local triaxial minima, energy surfaces, axial asymmetry shapes; deduced backbending phenomenon at about spin 18+ due to the alignment excitation of two quasi-neutrons of the high-j shell. Projected total-energy surface (PTES), total Routhian surface (TRS), and variation after projection (VAP) calculations. Comparison with experimental data.

Beyond-mean-field effects on nuclear triaxiality

NUCLEAR STRUCTURE 170,172,174,176,178W; calculated level energies, transition quadrupole moments, and projected total energy surfaces (PTES) in (ϵ2, γ) plane for positive-parity yrast bands up to 20+, level energies of γ bands. Investigated beyond-mean-field effects on nuclear triaxiality by projected total energy surface, based on the triaxial projected shell model and hybridized macroscopic-microscopic method. Comparison with experimental data.
