摘要
以^(197)Au为标准,用飞行时间方法,测量了10—100keV能区,~3Nb、^(169)Tm、~1Ta、Ag、Hf和W的中子俘获截面.通过~7Li(p,n)~7Be反应产生运动学准直中子,用两个Moxon—Rae探测器探测俘获事件,其结果与有关文献值作了比较.
The neutron capture cross sections of 93Nb, 169Tm, 181Ta, Ag, Hf and W were measured with respect to that of 197Au in the energy range from 10 to 100 keV using the time-of-flight method. Kinematically collimated neutrons were produced via the 7Li(p, n)7Be reaction. Capture events were detected with two Moxon-Rae detectors.The results were compared with the data from other authors.
