Recent advances in the physics of nuclei at high spin are presented. In particular the new phenomena observed by the latest generation of γ-rays spectrometers are discussed. An overview of experimental and theoretical treatment of "backbending·'' effect, quasiparticle alignment and band crossing is described in more detail. The outlines of the Cranked Shell Model, which is a successful framework for the interpretation of experimental data, are also reported.

Barrier Model

This paper is aimed to calculate neutron induced fission cross section using TALYS nuclear reaction code by utilizing new fission barrier model parameter. The new fission barrier model is based on minimization method of action functional of deformed nucleus fission trajectory in configuration of space from ground state to the exit barrier. New fission barrier parameter that obtained from this new model will be fed into the TALYS code to calculate the fission cross section of Th-232 and U-238 through statistical method. The result shows a better agreement with ENDF data compared to that of ETFSI (Extended Thomas-Fermi and Strutinsky Integral) or Mamdouh model of fission barrier for energy between 2 and 10 MeV.

Role of higher-multipolarity deformations of a nucleus in its (static) fission-barrier height [Formula: see text] is studied. The study is done within a macroscopic-microscopic approach. A heavy deformed nucleus 250 Cf is taken for the analysis. It is found that, in the case of axially symmetric shapes, the inclusion of higher-multipolarity deformations increases [Formula: see text].

Anisotropic Oscillator

The Kelvin circulation vector is the hermitian kinematical observable that measures the true character of nuclear rotation. For a rotating deformed nucleus modeled by a selfconsistent cranked anisotropic oscillator mean field with BCS pairing, the expectation value of the Kelvin circulation operator depends upon the deformation and upon the strength of the pairing field. For zero pairing, the circulation acquires its rigid rotor value. As the pairing field increases, the circulation tends to zero, the irrotational flow limit. At critical values of the pairing field, the deformation and circulation make abrupt phase transitions.
