MEASUREMENT OF THE NEUTRON CAPTURE CROSS SECTION OF ~(18)Ta
-
摘要: 用“瞬发γ射线法”,测量了 10—100 keV能区~(181)Ta的中子俘获截面。选择~(197)Au的俘获截面作为标准。用~7Li(p,n)~7Be反应产生中子。俘获γ事件用二个Moxon-Rae探测器探测。测量结果与近期其他作者的数据作了比较。Abstract: The neutron capture cross section of ~(181)Ta is measured in the 10 to 100 keVneutron energy range, using the prompt gamma-ray method. The capture crosssection of ~(197)Au was chosen as standard. The neutrons are produced via the ~7Li(p, n) ~7Be reaction. capture events are detected by two Moxon-Rae detectors. Theresults are compared with recent data of other authors.
