Particle-core coupling calculations have been made for the h/sub 9/2/ bands in the odd-Tl isotopes (A = 191--197) and the h/sub 11/2/ bands in the odd-Au isotopes (A = 189--195). The even-mass Hg core descriptions were taken from previous proton-neutron interacting boson model calculations, and thus a comparison between the experimental and calculated level schemes for the Tl and Au isotopes can be interpreted as a test of the core description. A predicted transition from positive Q(2/sup +/) near A = 195 to negative Q(2/sup +/) near A = 191 is not borne out by the odd-A data. These results, combined with new proton-neutron interacting boson model calculations, indicate that the Hg isotopes are more U(5) than O(6) in character.
