A particle plus triaxial rotor model was applied to odd‐odd nuclei in theA∼ 130 region in order to study the unique parity&pgr;h11/2⊗&ngr;h11/2rotational bands. With maximum triaxiality assumed and the intermediate axis chosen as the quantization axis for the model calculations, the two lowest energy eigenstates of a given spin have chiral properties. The independence of the quantityS(I)on spin can be used as a new criterion for chirality. In addition, a diminishing staggering amplitude ofS(I)with increasing spin implies triaxiality in neighboring odd‐Anuclei. Chiral quartet bases were constructed specifically to examine electromagnetic properties for chiral structures. A set of selection rules unique to chirality was derived. Doublet bands built on the&pgr;g9/2⊗&ngr;h11/2configuration have been discovered in odd‐odd104Rhusing the96Zr(11B, 3n)reaction. Based on the discussed criteria for chirality, it is concluded that the doublet bands observed in104Rhexhibit characteristic chiral properties suggesting a new region of chirality aroundA∼110. In addition, magnetic moment measurements have been performed to test the&pgr;h11/2⊗&ngr;h11/2configuration in128Csand the&pgr;g9/2⊗&ngr;h11/2configuration in104Rh. © 2003 American Institute of Physics
