• odd-odd Cs isotopes

Properties of the chair doublet bands of the odd-odd Cs isotopes built on the pi h(11/2) circle times nu h(11/2) configuration are investigated systematically within the supersymmetry scheme including many-body interactions and possessing the SO(5)(or SU(5)) symmetry on the rotational symmetry. Quantitatively good results of the energy spectra, the energy staggering parameter as a function of the spin are obtained. The calculation shows that the stronger competition between the pairing and anti-pairing effects and the SU(3) symmetry broking more seriously exist in the stable chiral structure.
