Examining the chiral geometry in 104Rh and 106Rh

Abstract

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 $A\sim 100$ 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.
