Composite chiral bands, corresponding to the $\pi g_{9/2}\nu (h_{11/2})^2$ quasiparticle configuration, were observed in $^{103}Rh and $^{105}$Rh. The behaviour of these bands were compared with that of the chiral bands with $\pi g_{9/2}\nu h_{11/2}$ quasiparticle configuration observed in the odd-odd $^{102}Rh and $^{104}Rh nuclei. This comparison shows in a model independent way that the energy separation pattern of the chiral partner bands depends strongly on the properties of the triaxial core while the dependence on the valence quasiparticle coupling and on the Fermi level is weaker.< Réduire
