Abstract：
The systematics of signature inversion of the πg_9/2⊙υh_11/2 configuration bands in Ag, Rh and Tc isotopes is studied. The inversion point shifts toward the lower spin with neutron number increasing for isotopes and shifts toward the higher spin with proton number increasing for isotones. This systematic feature of signature inversion in A～100 mass region is well explained by the competition between the p-n residual interaction and the Coriolis force.
