High-spin states in the odd-odd 182Au nucleus have been investigated using the 152Sm( 35Cl, 5n ) 182Au reaction through X- and - -t coincidence measurements. Rotational bands based on the and configurations have been identified. It is found that the two bands show characteristics of low-spin signature inversion. The observed signature inversion can be well reproduced by pairing-deformation self-consistent cranking Woods-Saxon calculations.
