Abstract

High-spin states in the odd-odd Au nuclei 190,192,194Au have been populated using (α, xn) reactions and studied by means of in-beam γ-ray and e spectroscopic methods. In each nucleus two negative-parity rotation-aligned bands were observed, which are based on an 11 isomer and a 12 state, respectively. They may have a configuration resulting from the coupling of a h112 proton-hole and an i132 neutron-hole coupled to a predominantly oblate core in agreement with recent theoretical predictions in the framework of the triaxial-rotor-plus-particle model. Furthermore, side structures based on 15(+) states were established up to spins of I = (20) and (22) in 190,192Au, respectively. The 15(+) and 17(+) members are considered to have a (πh112−1vi132−2(vj) configuration (j = P12, P32 or f52). In the nucleus 194Au a positive-parity rotation-aligned band based on a 7+ state was established up to the 13+ state. This band may have predominantly a (vi132−1πd32−1) configuration.
