high spin states in the neutron rich nucleus 191os has been populated for the first time using the82se+192os deep-inelastic reaction at 460 mev beam energy using the alpi accelerators at the laboratorynazionali di legnaro, italy. high fold γ-γ coincidences were acquired with the 4π spectrometer gaspdetector array, consisting of 40 compton-suppressed, large-volume germanium detectors with an inn...

By means of periodic orbit theory and deformed cavity model, we have investigated semiclassical origin of superdeformed shell structure and also of reflection-asymmetric deformed shapes. Systematic analysis of quantum-classical correspondence reveals that bifurcation of equatorial orbits into three-dimensional ones play predominant role in the formation of these shell structures. PACS number: 2...

The knowledge on stellar weak interaction processes is one of the most important ingredients for resolving astrophysical questions. Study of these rates is essentially a nuclear structure problem, in which the actual decay rates are determined by the microscopic inside of nuclear many-body systems. For many astrophysically-interested questions, information on detailed nuclear level structure at...

We use the considered axial deformed relativistic mean field theory to perform system-atical calculations for Z = 112 and 104 isotopic chains with force parameters NL3, NL-SH and NL-Z2 sets. Three deformed chains (oblate, moderate prolate and super-deformed chain) are found for Z = 112 and 104 isotopic chains. It is found that there is a chain of super-deformed nuclei which can increase the sta...

Performing shell model calculations for heavy nuclei is a long-standing problem in nuclear physics. The shell model truncation in the configuration space is an unavoidable step. The Projected Shell Model (PSM) truncates the space under the guidance of the deformed mean-field solutions. This implies that the PSM uses a novel and efficient way to bridge the two conventional methods: the deformed ...
