The half-life ({ital T}{sub 1/2}) and {ital g} factor of the 2002 keV 11{sup {minus}} isomer in the odd-odd nucleus {sup 92}Tc produced by the pulsed heavy-ion reaction {sup 68}Zn({sup 28}Si,{ital p}3{ital n}){sup 92}Tc have been measured using time differential perturbed angular distribution method. The measured {ital T}{sub 1/2} value is 3.15(20) ns. From the observed spin precession frequency {omega}{sub {ital L}} of a {sup 92}Tc recoil implanted into a ferromagnetic Ni host, we obtain the {ital g} factor to be 0.806(20). The measured value of the {ital g} factor is in good agreement with a shell model analysis carried out using {pi}({ital p}{sub 1/2}{ital g}{sub 9/2}) and {nu}({ital p}{sub 1/2}{ital g}{sub 9/2}) orbitals for the proton particles and neutron holes outside the {sup 88}Sr core. {copyright} {ital 1996 The American Physical Society.}
