Excitation functions were measured for the production of 106m,105Ag, 103,101,100Pd, 105,102,101m,100,99Rh and 97Ru via proton-induced activation reactions on natural silver using a stacked foil technique in the energy range 11-80 MeV. The residual activity measurements were carried out nondestructively by the high-resolution HPGe gamma-ray spectroscopy. Thick target integral yields were deduced using the measured cross-sections from the respective threshold energies of the investigated reactions up to 80 MeV. The present work gives new results for the investigated radionuclides. The data in MENDL-2P deduced with the theoretical model code ALICE-IPPE are consistent in shape with the measured values, but show disagreement in magnitude.
采用叠层箔技术，在11 - 80 MeV能量范围内，测量了质子轰击天然银引发的活化反应生成106m、105Ag、103、101、100Pd、105、102、101m、100、99Rh和97Ru的激发函数。通过高分辨率HPGeγ射线光谱法对剩余活度进行了无损测量。利用从所研究反应的各自阈能到80 MeV的测量截面，推导出厚靶积分产额。本工作给出了所研究放射性核素的新结果。用理论模型代码ALICE - IPPE推导的MENDL - 2P中的数据在形状上与测量值一致，但在量级上存在差异。
