Static quadrupole moments (Q) of 8/sup +/ isomers in /sup 88,90/Zr and the (21/2)/sup +/ isomer in /sup 91/Zr, as well as Q ratios of 8/sup +/ isomers in /sup 90,92,94/Mo, have been measured with the time-differential perturbed angular-distribution technique. The isomers were excited by pulsed heavy-ion beams and recoil implanted into single crystals of Zr in which their quadrupole precession was observed. Our results, the first such data for high-spin isomers in the g/sub 9/2/ shell, yield large E2 effective charges for the g/sub 9/2/ proton and the g/sub 9/2/ neutron. The systematics of these charges are comprehensively explained by particle-vibration coupling and the blocking effect.
