| 摘 要： | 通过测量质子轰击固体薄靶产生的特征X射线和卢瑟福散射粒子,确定了在1.6-2.4MeV能区内质子激发Ag、Cu、Ni等元素的K壳层电离截面,测量误差约为10%。用OPSSR、PWBA等模型做了相应的计算,OPSSR计算结果与实验符合得较好,PWBA计算结果与实验相比有一致性偏高。

| Abstract: | The measurements of K-shell ionization cross-section induced by 1.6~2.4MeVproton have been performed for Ag, Cu, Ni with the errors about 10%. Comparisonof ionization cross-sections for self-supporting thin foil and the foil with Carbonbacking shows good agreements. The prediction of the model CPSSR is consistentwith the results of measurement and the prediction of the PWBA is higher thanexperimental data overall. |
