Experimental nuclear moments of inertia at high spins along the yrast line have been determined for a large number nuclei. They are found to systematically differ from rigid-body values. The difference is attributed shell effects which well described by rotating Woods-Saxon potential. data and quantal calculations interpreted means semiclassical periodic orbit theory. From this new perspective, features in as function neutron spin their relation energies can be understood. Gross persist up...
Level schemes of even–even neutron-rich 88-92 Kr and 86 Se have been investigated by measuring triple-γ coincidence data from the spontaneous fission 252 Cf with Gammasphere detector array. The level scheme 88 has extended up to 7169 keV state. Several new excited states transitions identified in 90,92 . Spins parities assigned levels these nuclei following regional systematics angular correlation measurements. structures N = 52, 54, , Sr isotones are discussed.
Energies and excitation probabilities of compressional vortical collective 1- states are calculated in the frame time-dependent Hartree-Fock theory. The method Wigner function moments is used to find solutions an equation for a density matrix. Good agreement with experiment obtained low-energy isoscalar dipole resonance 208Pb. toroidal predicted.
Various fission processes are described in terms of high-dimensional potential energy surface the frame Strutinsky shell correction method for actinide region. The complete deformation space is necessary to study minima responsible cluster radioactivity, cold and multi-fragmentation valleys. nuclear shape families different configurations obtained without any specific change parameters. coordinate system based on Cassini ovaloids makes it possible increase number independent parameters...
A new ternary decay channel connected with magic constituents from Cf and U has been observed in recent experiments. It was called Collinear Cluster Tripartition (CCT) because the products fly apart almost collinearly. is a of fissioning system into three fragments comparable masses strongly elongated configuration. total yield CCT events found at order 10 -3 per binary fission. The first theoretical description high lying energy minima on potential landscape are presented for . They have...
