Abstract: We report the results of recent measurements of the spectroscopic quadrupole moments of high-spin isomers. For the K-pi = 35/2(-) five-quasiparticle isomer in W-179 we measured Q(B) = 4.00 ((+0.83)(-1.06)) eb. It corresponds to a smaller deformation compaxed to the ground states of the W isotopes and is in disagreement with the current theoretical predictions. We also measured the quadrupole moment of the I-pi = 11(-) isomer in Pb-196, Q(s) = (-)3.41(66) eb. It has the same proton (s(1/2)(-2)h(9)/(2)i(13/2)) configuration as the one suggested for the 11 = 16(-) magnetic bandhead which allows to deduce the quadrupole moment of the 16(-) state as Q(s) = -0.316(97) eb. This small value proves the near sphericity of the bandhead.
