The g factors and quadrupole moments of the 21/2 − and 33/2 + isomers in 193 Pb have been measured by the time-differential perturbed γ-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), |Q(33/2 +)| = 0.45(4) eb. The results support the three-neutron configurations (1i 13/2) 2 12 + ⊗ 3p 3/2 and (1i 13/2) 3 for the 21/2 − and 33/2 + states, respectively. The quadrupole moment of the 12 + isomer in 194 Pb described by the twoneutron (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 BCS approach in a number-projected one-and three-quasiparticle neutron space, and in the frame of the pairing plus quadrupole tilted-axis cranking model.
