High-spin level scheme and decay of the 67-μms isomer in 142Pm
PHYSICAL REVIEW C 70, 014304 (2004)，-0001，（）：
An in-beam γ-ray spectroscopy experiment for 142Pm has been performed via the 128Te (19F, 5n) reaction at beam energies of 75 MeV through 95 MeV. Excitation functions and γ-γ coincidences have been measured. Detailed analysis of γ-γ coincidence relationships leads to a revised high-spin level scheme for 142Pm. The πh11/2 vh11/2−1 multiplet in this nucleus has been identified and the discussion is based on a systematic of corresponding states in neighboring odd-odd nuclei. The previously known 67-μs isomer and associated decay grays have been placed into the new level scheme. This long-lived isomer is proposed to be a four-hole state with predominantly the （πg7/2−2-1d5/2-2vh11/2-1) 13-configuration.
