چکیده

Two isomeric states have been identified in 255 Lr. The decay of the isomers populates rotational structures. Comparison with macroscopic-microscopic calculations suggests that the lowest observed sequence is built upon the [624]9/2 + Nilsson state. However, microscopic cranked relativistic Hartree-Bogoliubov (CRHB) calculations do not reproduce the moment of inertia within typical accuracy. This is a clear challenge to theories describing the heaviest elements.

1 4 A pr 2 00 9 Multi - quasiparticle γ - band structure in neutron - deficient Ce and Nd isotopes

The newly developed multi-quasiparticle triaxial projected shell-model approach is employed to study the high-spin band structures in neutron-deficient even-even Ceand Nd-isotopes. It is observed that γ-bands are built on each intrinsic configuration of the triaxial mean-field deformation. Due to the fact that a triaxial configuration is a superposition of several K-states, the projection from ...

Understanding the different rotational behaviors of 252 No and 254 No

Total Routhian surface calculations have been performed to investigate rapidly rotating transfermium nuclei, the heaviest nuclei accessible by detailed spectroscopy experiments. The observed fast alignment in No and slow alignment in No are well reproduced by the calculations incorporating high-order deformations. The different rotational behaviors of No and No can be understood for the first t...

بازنگری بر خانواده مرموز Hg: یک مطالعه جامع براساس نظریه تابعی چگالی

  We review theoretical investigations of high-temperature superconductors which have been performed by density functional theory. The main subject of our study is the Hg-based family of the superconducting cuprates, which demonstrates unusual and still puzzling properties. We show that the first-principles approach is able to describe the effects of chemical doping and pressure on the structur...

SPECTROSCOPY OF SUPERDEFORMED Pb ISOTOPES

In the mass region around A = 190 about 70 superdeformed (SD) rotational bands are known in 25 different nuclei [1]. In many cases several bands have been found which are built on excited states in the SD potential energy minimum. The nature of these excitations has been the subject of experimental and theoretical investigations in recent years. In the odd-even and odd-odd nuclei it seems clear...

Restoration of the Broken D2-symmetry in the Mean Field Description of Rotating Nuclei

Signature effects observed in rotational bands are a consequence of an inherent D2-symmetry. This symmetry is naturally broken by the mean field cranking approximation when a tilted (non-principal) axis orientation of the nuclear spin becomes stable. The possible tunneling forth and back between the two symmetry-related minima in the double-humped potential-energy surface appears as a typical b...
