A previously unreported isomer has been identified in {sup 99}Mo at an excitation energy of E{sub x}=3010 keV, decaying with a half-life of T{sub 1/2}=8(2) ns. The nucleus of interest was produced following fusion-fission reactions between a thick {sup 27}Al target frame and a {sup 178}Hf beam at a laboratory energy of 1150 MeV. This isomeric state is interpreted as an energetically favored, maximally aligned configuration of {nu}h{sub (11/2)} x {pi}(g{sub (9/2)}){sup 2}.
