Level structure and excitation energy of a high-spin isomer in Ho150

The high-spin states of Ho-150 have been studied by the Pr-141(O-16,7n)Ho-150 reaction at a beam energy of 165 MeV using techniques of in-beam gamma-ray spectroscopy. Measurements of gamma-gamma-t coincidences were performed. Based on the coincidence relations of gamma rays, a level scheme was constructed up to 11.25 MeV. The excitation energy of high-spin isomer was determined to be 8.412 MeV with a half-life of 787 +/- 36 ns. The experimental results were compared with deformed independent particle model (DIPM) calculations. The excitation energy of the state with the possible configuration of the high-spin isomer in Ho-150 was discussed.
