Abstract: The g factors and quadrupole moments of the 21/2(-) and 33/2(+) isomers in Pb-193 have been measured by the time-differential perturbed gamma-ray angular distribution method as g(21/2(-))=-0.059(11), \Q(21/2(-))\=0.22(2) eb and g(33/2(+))=-0.171(9), parallel toQ(33/2(+))\=0.45(4) eb. The results support the three-neutron configurations (1i(13/2))(12)(+2)x3p(3/2) and (1i(13/2))(3) for the 21/2(-) and 33/2(+) states, respectively. The quadrupole moment of the 12(+) isomer in Pb-194 described by the two-neutron (1i(13/2))(2) configuration has been remeasured as \Q(12(+))\=0.48(3) eb in perfect agreement with the previous data. The experimental results are discussed within a microscopic Bardeen-Cooper-Schrieffer approach in a number-projected one- and three-quasiparticle neutron space, and in the frame of the pairing plus quadrupole tilted-axis cranking model.
