研究了利用8mev质子束的带电粒子活化分析（CPAA）用于一般元素定量。我们参考布鲁克海文国家实验室国家核数据中心提供的核数据库，积累了反应截面和核衰变数据。利用该数据库，我们推导出了每种核素单元素样品的测定灵敏度。结果表明，虽然随着靶核变重，测定灵敏度逐渐降低，但可以对包括重核区在内的所有元素进行CPAA分析。可以得出结论，CPAA可以应用于大多数稳定核，是中子活化分析的替代方法之一。
Charged particle activation analysis (CPAA) utilizing an 8 MeV proton beam has been studied for general elemental quantification. We accumulate the reaction cross section and nuclear decay data by referring to nuclear database supplied by National Nuclear Data Center in Brookhaven National Laboratory. By using the database we have derived determination sensitivity of single element samples for each nuclide. The result indicates that, while the determination sensitivity tends to decrease gradually as the target nucleus becomes heavy, the CPAA analysis is possible over the whole elements including the heavy nuclear region. It may be concluded that CPAA can be applied to most of the stable nuclei and is one of the alternative methods to neutron activation analysis.
