摘要:

用叠箔辐照技术和γ能谱测量了80 MeV以下的质子在钯上引起的核反应的活化截面。束流强度,入射能量和能量退化的控制方法的基础上通量恒定通过归一化的监测反应的激发函数并行测量。测量了${}^{104m,104g,105}$ ${}^{g,106m,110m}$ Ag、${}^{100,101}$ Pd、${}^{99m,99g,100,}$ ${}^{101m}$ ${}^{,101g,102m,102g,105}$ Rh和${}^{103,}$ ${}^{97}$ Ru放射性同位素的直接和累积截面的激发函数。将截面数据与TENDL-2014和-2015库的理论预测进行比较。对于实际应用,厚靶产额来自于测量的激发函数。在医用放射性核素生产领域的应用进行了简短的讨论。

英文摘要:

Activation cross sections of proton induced nuclear reactions on palladium were measured up to 80 MeV by using the stacked foil irradiation technique and gamma ray spectrometry. The beam intensity, the incident energy and the energy degradation were controlled by a method based on flux constancy via normalization to the excitation functions of monitor reactions measured in parallel. Excitation functions for direct and cumulative cross-sections were measured for the production of ${}^{104m,104g,105}$${}^{g,106m,110m}$Ag, ${}^{100,101}$Pd, ${}^{99m,99g,100,}$${}^{101m}$${}^{,101g,102m,102g,105}$Rh and ${}^{103,}$${}^{97}$Ru radioisotopes. The cross section data were compared with the theoretical predictions of TENDL-2014 and -2015 libraries. For practical applications thick target yields were derived from the measured excitation functions. Application in the field of medical radionuclide production is shortly discussed.
