Chiral doublet bands in odd-odd nuclei

The criteria for chiral doublet bands based on one particle and one hole coupled to a triaxial rotor have been summarized. Candidate chiral doublet bands in A similar to 100 and 130 odd-odd nuclei were checked against these chiral criteria. Two representative cases, nearly degenerate Delta I = 1 doublet bands in (126)Cs and 106 Rh were investigated in the two quasiparticles coupled with a triaxial rotor model. After including the pairing correlation, good agreement has been obtained between the calculated results and the data available, which supports the interpretation of observed doublet bands as chiral bands.
