The γ-ray decay of excited states of the two-proton hole nucleus, 206Hg, has been identified using Gammasphere and 208Pb+238U collisions. The yrast states found include a T1/2 = 92(8)ns 10+ isomer located above the known 5- isomer. The B(E2;10+→8+) strength is used to derive the quadrupole polarization charge induced by the h11/2 proton hole. Also, the implied quadrupole moment has been used to provide an absolute scale for the electric field gradient of Hg in Hg metal.
