High-spin level scheme of odd-odd Pm-142

The level structure of doubly odd nucleus (142) Pm has been studied via the (128) Te((19) F, 5ngamma)(142) Pm reaction in the energy region from 75 to 95MeV. In-beam gamma rays were measureed including the excited function, gamma-ray singles and gamma-gamma coincidences in experiment. The level scheme of 142 I'm has been extended up to excitation energy of 7030.OkeV including 25 new gamma rays and 13 new levels. Based on the measured gamma-ray anisotropies, the level spins in (142) Pm have been suggested.
