Phenomenological Analysis and Determination of Spins for Superdeformed Bands in the Mass-190 Region

  • Fifteen superdeformed bands in seven nuclei of the mass-190 region are analyzed by means of the phenomenological model.An overall and excellent agreement between the calculated and observed spectra Er,kinematic moment of inertia J(1) and dynamic moment of inertia J(2) is obtained for all superdeformed bands in the mass-190 region.

Abstract: Fifteen superdeformed bands in seven nuclei of the mass-190 region are analyzed by means of the phenomenological model.An overall and excellent agreement between the calculated and observed spectra Er,kinematic moment of inertia J(1) and dynamic moment of inertia J(2) is obtained for all superdeformed bands in the mass-190 region.
