The ^14N beam was obtained from the HI-13 tandem accelerator of China Institute of Atomic Energy, Beijing. The target is an enriched ^130Te metallic foil of 1.67mg/cm^2 thickness with a 10.37mg/cm^2 Pb backing. Measurements of γ-ray singles, γ-γ-t coincidences and γ-ray excitation function were performed with twelve BGO(AC)HPGe detectors. Based on detailed analysis of γ-γ coincidence relationships,展开更多
The high-spin states of very neutron-deficient doubly odd nucleus ^190T1 have been investigated via the ^160Gd(^35C1, 5n)^190T1 reaction by using techniques of in-beam γ-ray spectroscopy.
