Theoretical Research on Traxial Superdeformed Band and High Spin State Nuclei in 168Lu

  • The three dimensional Total Routhian Surface calculations are carried out to analyze the four rotational bands in 168Lu observed recently. One of these four bands is identified as tri-axial super-deformed band, which is consistent with the experimental assignment. The values of its deformation parameters are derived respectively from the analysis. The quasi-particle energy variation with the rotational frequency is explained reasonably.The reason, why the signature partner of the fourth band has not been found experimentally, is also given.

Abstract: The three dimensional Total Routhian Surface calculations are carried out to analyze the four rotational bands in 168Lu observed recently. One of these four bands is identified as tri-axial super-deformed band, which is consistent with the experimental assignment. The values of its deformation parameters are derived respectively from the analysis. The quasi-particle energy variation with the rotational frequency is explained reasonably.The reason, why the signature partner of the fourth band has not been found experimentally, is also given.
