A revised decay scheme of the 16-min isomer Ta/sup 182//sup m/ in volves three states of Ta/sup 182/ at excitation energies of 147, 319, and 503 kev. Transition multipolarities were classified by measuring both gamma -ray coincidences and internal conversion electrons. The 503-kev isomeric atate decays mainly (98%) by a 184-kev E3 transition to the 319-kev state. This 319- kev atate decays mainly (94%) to the 147kev state by means of a 172-kev transition that is predominantly M1. The 147-kev transition to the ground state is also predominantly M1. Two of the three possible crossover transitions were observed; a 356-kev M4 transition originates at the isomeric level and a 319-kev E2 transition connects the second excited state with the ground state. The 147- kev and the 319-kev states are probably the first and second excited rotational states of the ground-state configuration. The relevant rotational parameters are of particular interest because very little is known about moments of inentia for odd-edd nuclei. The relative prohabilities were determined for pile neutron activation of the 16-min isomer, Tai/sup 182//sup m/, and the 112-day ground state Ta/sup 18/ s/sup 2/. (auth)
