The quadrupole interaction of high-spin isomers in Pb-193 implanted into solid Hg cooled at a temperature T=170 K has been investigated by the time-differential perturbed gamma-ray angular-distribution method. Spectroscopic quadrupole moment values of \Q\=0.22(2) eb and 0.45(4) eb have been deduced for the 21/2(-) and 33/2(+) three-neutron states, respectively. A much higher value \Q(s)\=2.84(26) eb has been determined for the 29/2(-) isomer, the band head of a magnetic rotational band.
