Abstract
A particle plus triaxial rotor model was applied to odd-odd nuclei in the A {approx} 130 region in order to study the unique parity {pi}h11/2x{nu}h11/2 rotational 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 quantity S(I) on spin can be used as a new criterion for chirality. In addition, a diminishing staggering amplitude of S(I) with increasing spin implies triaxiality in neighboring odd-A nuclei. 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 {pi}g9/2x{nu}h11/2 configuration have been discovered in odd-odd 104Rh using the 96Zr(11B, 3n) reaction. Based on the discussed criteria for chirality, it is concluded that the doublet bands observed in 104Rh exhibit characteristic chiral properties suggesting a new region of chirality around A {approx}110. In addition, magnetic moment measurements have been performed to test the {pi}h11/2x{nu}h11/2 configuration in 128Cs and the {pi}g9/2x{nu}h11/2 configuration in 104Rh.
