摘要

<正>High-spin Level structure of 188T1 has been studied via the 157Gd(35Cl, 4n) fusion-evaporation reaction at beam energy of 170 MeV. The 35Cl beam was provided by the JAERI tandem accelerator and impinged on an enriched 157Gd metallic foil of 2. 0 mg/cm2 thickness with a 6. 5 mg/cm2 Pb backing.γ-γ-t and X-γ-t measurements were performed by aγ-ray detector array consisting of 13 BGO(AC) HPGe's and 3 LOAX detectors. A total of about 270×106 coincidence events were accumulated. Prior to this work, an early in-
