Algebraic Model Description of High Spin Superdeformed Bands

  • Status of the investigation on superdeformed nuclear bands are surveyed briefly.An algebraic model which can describe the ΔI=4 bifurcation and the identical bands is proposed.The calculated results indicate that the ΔI=4 bifurcation may come from the perturbation holding the SO(5)(or SU(5)) symmetry.Meanwhile the identical bands result from that the mean field for the superdeformed bands to build upon may possess supersymmetry.

Abstract: Status of the investigation on superdeformed nuclear bands are surveyed briefly.An algebraic model which can describe the ΔI=4 bifurcation and the identical bands is proposed.The calculated results indicate that the ΔI=4 bifurcation may come from the perturbation holding the SO(5)(or SU(5)) symmetry.Meanwhile the identical bands result from that the mean field for the superdeformed bands to build upon may possess supersymmetry.
