..gamma.. rays emitted in the decay of 9.4-h /sup 201/Pb were studied with Ge(Li) and NaI(Tl) detectors in singles, anti-Compton, anticoincidence, and integral coincidence configurations. The construction of a consistent decay scheme including 66 of the 74 ..gamma.. rays observed in the decay of /sup 201/Pb was also aided by a two-dimensional ..gamma..-..gamma.. coincidence experiment of 4096 x 4096 channels using two Ge(Li) detectors. The proposed levels in /sup 201/Tl lie at 0, 331.15, 692.40, 1098.4, 1134.8, 1157.4, 1238.8, 1277.1, 1290.0, 1330.4, 1401.2, 1420.0, 1445.8, 1479.9, 1575.1, 1617.4, 1639.5, 1672.0, and 1755.3 keV with possible additional levels at 1550.5 and 1712.5 keV. Using existing conversion-electron data, conversion coefficients were calculated and multipolarity assignments proposed for 25 transitions. Based on these multipolarities, photon branching ratios, and logft values, unique spin and parity assignments have been made for several states and limits placed on others. The resulting decay scheme is compared with recent theoretical calculations of level energies and ..gamma.. transition probabilities, using the intermediate-coupling unified model.
