摘要

<正>The high-spin states in 139Ce have been populated via the 130Te(12C, 3n) 139Ce reaction by using techniques of in-beamγ-ray spectroscopy. The 12C beam at 50 MeV energy was provided by the HI-13 tandem accelerator at the China Institute of Atomic Energy, Beijing. The 130Te target is an enriched metallic foil of about 1. 4 mg/cm2 thickness with a 9 mg/cm2 197Au backing to stop the recoiling nuclei. 14 BGO(AC)
