总结了基于一粒子一空穴耦合三轴转子的手征二重带判据。用这些手征判据检验了两个典型的A\sim100 $奇-奇核，即$^{104}$Rh和$^{106}$Rh中的近简并$\Delta I =1$二重带.结果表明，$^{106}$Rh具有比$^{104}$Rh更好的手征几何构型，尽管与$^{106}$Rh中的双峰能量分离相比，$^{104}$Rh中的能量接近简并态。
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 $A\sim100$ odd-odd nuclei, nearly degenerate $\Delta I =1$ 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 $^{104}$Rh, although the energy near degeneracy is achieved in $^{104}$Rh in comparison with the constant energy separation of doublet bands in $^{106}$Rh.
