description Several new or poorly characterized neutron-rich nuclides have been produced and studied at the Brookhaven Medium Energy Intense Neutron facility, MEIN. /sup 190/W decays with T/sub 1/2/=30.0+or-1.5 min, E /sub beta /=0.93+or-0.07 MeV, and gamma 's of 157.6 and 162.1 keV. /sup 196/Os decays with T/sub 1/2/=35.0+or-0.4 min and gamma 's at 126.1, 200.7, 207.0, 257.0, 315.3, 407.6, 522.2, and 628.9 keV. /sup 230/Ra decays with T/sub 1/2/=93+or-2 min to 122+or-3 sec /sup 230/Ac; gamma -ray energies and intensities are tabulated. A decay scheme is proposed for /sup 190/W, and many of the transitions following the decay of /sup 230/Ac are between known levels in /sup 230/Th. (15 refs).
