Configuration Structure of Superdeformed Bands in A~190 Mass Region

  • Using the particle-number conservation method for treating the cranked shell model with pairing interaction, we systematically investigate the variations of the moments of inertia, the angular moment alignment and the signature splitting with rotational frequencies for superdeformed bands in the A~190 mass region. According to our calculated results, we provide a global description of the configuration structure of superdeformed bands in the A~190 mass region. Most superdeformed bands are located at the strong-coupling orbits, such as neutron [512]5/2, [624]9/2. A few superdeformed bands lie on high j orbits, i.e., neutron [761]3/2, [752]5/2. Our calculated configuration assignments give a satisfactorily explanation to the general behavior, the anomalous change and the band crossing of superdeformed bands in the A~190 mass region.

Abstract: Using the particle-number conservation method for treating the cranked shell model with pairing interaction, we systematically investigate the variations of the moments of inertia, the angular moment alignment and the signature splitting with rotational frequencies for superdeformed bands in the A~190 mass region. According to our calculated results, we provide a global description of the configuration structure of superdeformed bands in the A~190 mass region. Most superdeformed bands are located at the strong-coupling orbits, such as neutron [512]5/2, [624]9/2. A few superdeformed bands lie on high j orbits, i.e., neutron [761]3/2, [752]5/2. Our calculated configuration assignments give a satisfactorily explanation to the general behavior, the anomalous change and the band crossing of superdeformed bands in the A~190 mass region.
