Excited states of Hg202 have been studied via the C12(Hg202,Hg∗202) Coulomb excitation reaction at a beam energy of 890 MeV. The γ-ray transitions from the excited states of Hg202 were detected by the Gammasphere array. The intensities of the observed γ rays determined the relative populations of the excited states which were used to extract the absolute M1 and E2 transition strength distributions for excited 2+ states of Hg202 up to 2 MeV. The measured absolute B(M1;27+→21+) strength of 0.18(8)μN2 indicates that the 27+ level of Hg202 is the main fragment of the proton-neutron mixed-symmetry 21,ms+ state. Upper limits for the F-spin mixing matrix elements of 202,204Hg are determined as well.
