Description of identical superdeformed bands with Delta I=4 bifurcation

With the supersymmetry scheme including many-body interactions, a parametrization of the excitation energy of superdeformed (SD) states is proposed. The identical SD bands with DeltaI = 4 bifurcation, Gd-149(1) -Gd-148(6) - Eu-148(1), are investigated. Quantitatively good results are obtained. The result shows that the parametrization can describe the identical SD bands and the DeltaI = 4 bifurcation simultaneously. It suggests that the DeltaI = 4 bifurcation in the SD bands may have a bearing on a perturbation exhibiting the SO(5) [or SU(5)] symmetry in the mean field and the identical bands may be interrelated with the supersymmetry.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000168059900033&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, NuclearSCI(E)21ARTICLE4null6
