Level structure and excitation energy of a high-spin isomer in Ho 150

The high-spin states of {sup 150}Ho have been studied by the {sup 141}Pr({sup 16}O,7n){sup 150}Ho 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 {sup 150}Ho was discussed.
