摘要: 用14MeV中子轰击Pt,通过198Pt(n,2p)反应产生197Os。用高纯锗探测器观测197Os的衰变γ射线,获得了10条新γ射线,并指定为197Os的衰变,测定它的半衰期为2.8±0.6min。根据γ(X)-γ符合测量,建议一个197Os的部分衰变纲图。Abstract: By irradiation of platinum with 14 MeV neutrons, ~(197)Os is produced through the reaction (n,2p). The γ rays following the β~- decay of ~(197)Os are investigated with HPGe detectors. The ten new γ rays are observed, and the half-life of ~(197)Os is 2.8±0.6 min. A partial decay scheme of ~(197)Os is proposed based on γ(X)-γ coincidence measurements.
