A theoretical study of the nuclear-reaction cross sections for proton-induced reactions on (63)Cu and (65)Cu was performed in the proton energy range from threshold values up to 50MeV. The produced nuclei were different isotopes of Zn, Cu, Ni, Co and Mn, some of which have important applications. The reaction cross-section calculations were performed using the ALICE-IPPE code, which depends on the pre-equilibrium compound nucleus model. This code is suitable for the studied energy and isotopic mass ranges. Approximately 14 excitation functions for the different reactions have been constructed from the calculated cross-section values. The excitation function curves for the proton reactions with natural copper targets have been constructed from those for enriched targets using the natural abundance of the copper isotopes. Comparisons between the calculated excitation functions with those previously experimentally measured are given whenever the experimental values were available. Some statistical parameters were introduced to control the quality of the fitting between both the experimental and the theoretical calculated cross-section values.
对质子能量范围从阈值到50MeV的质子诱发反应在(63)Cu和(65)Cu上的核反应截面进行了理论研究。产生的核是Zn、Cu、Ni、Co和Mn的不同同位素,其中一些具有重要应用。使用依赖于预平衡复合核模型的ALICE - IPPE代码进行反应截面计算。该代码适用于所研究的能量和同位素质量范围。从计算出的截面值构建了不同反应的约14个激发函数。利用铜同位素的天然丰度,从富集靶的激发函数构建了天然铜靶质子反应的激发函数曲线。只要有实验值,就给出计算出的激发函数与先前实验测量值之间的比较。引入了一些统计参数来控制实验和理论计算截面值之间拟合的质量。
