Abstract：
The criteria for chiral doublet bands obtained by assuming one proton (neutron) particle and one neutron (proton) hole sitting in a corresponding high-j shell coupled to a triaxial rotor with γ=30° have been summarized. Two representative cases in A～100 odd-odd nuclei, nearly degenerate ΔI=1 doublet bands in ¹⁰⁴Rh and ¹⁰⁶Rh are checked against these chiral criteria. It is shown that ¹⁰⁶Rh 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.
