摘要

The criteria for chiral doublet bands based on one particle and one hole coupled to a triaxial rotor have been summarized. Two representative cases in A ～ 100 odd-odd nuclei, nearly degenerate △I = 1 doublet bands in 104 Rh and 106 Rh, are checked against these chiral criteria. It is shown that 106 Rh possesses better chiral geometry than 104Rh, although the energy near degeneracy is achieved in 104Rh in comparison with the constant energy separation of doublet bands in 106Rh.
