本工作对40Ca(n,α)反应实验数据进行了收集、仔细分析和评价,利用最新标准进行了必要的修正,给出了新的评价截面以及协方差数据。对40Ca(n,α)反应共收集到12组实验数据,来自EXFOR库及学位论文,根据设备、中子源、测量方法、探测器、样品丰度、实验室、年代、标准截面阈能、半衰期等,对各家实验数据都进行了仔细的分析、评价,取舍和修正。
In this work, experimental data of 40Ca (n, α) reaction were collected, carefully analyzed and evaluated, the necessary amendments were made according to the latest standards, and new evaluation cross sections and covariance data were given. A total of 12 sets of experimental data were collected from the 40Ca (n, α) reaction from the EXFOR database and dissertations. Based on the equipment, neutron source, measurement method, detector, sample abundance, laboratory, Half-life and so on, each of the experimental data were carefully analyzed, evaluated, trade-offs and amendments.
