Abstract
Measurement of -ray distributions from the reaction confirms spin for the 3404-keV level and gives an unambiguous spin assignment of for the 3508-keV level. Measurement of lifetimes and mixing ratios show that both states have positive parity. The excitation energy and the enhanced strength of > 11 Weisskopf units for the to ground-state transition identify the level at 3508 keV as the member of a rotational band based on the ground state.
