Quadrupole moments and g factors for high-spin neutron isomers in $^{193}$Pb

The g factors and quadrupole moments of the 21/2{sup -} and 33/2{sup +} isomers in {sup 193}Pb have been measured by the time-differential perturbed {gamma}-ray angular distribution method as g(21/2{sup -})=-0.059(11), |Q(21/2{sup -})|=0.22(2) eb and g(33/2{sup +})=-0.171(9), |Q(33/2{sup +})|=0.45(4) eb. The results support the three-neutron configurations (1i{sub 13/2}){sub 12{sup +}}{sup 2}x3p{sub 3/2} and (1i{sub 13/2}){sup 3} for the 21/2{sup -} and 33/2{sup +} states, respectively. The quadrupole moment of the 12{sup +} isomer in {sup 194}Pb described by the two-neutron (1i{sub 13/2}){sup 2} configuration has been remeasured as |Q(12{sup +})|=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.
