Fe, Cu, and Al stacked foils were irradiated by 90 MeV protons at the Los Alamos Neutron Science Center's Isotope Production Facility to measure nuclear cross sections for the production of medically relevant isotopes, such as Mn, Mn, Cr, Co, Co and Ni. The decay of radioactive isotopes produced during irradiation was monitored using high-purity germanium gamma spectroscopy over the months following irradiation. Proton fluence was determined using the Al(p,x)Na, Cu(p,x)Zn Cu(p,x)Zn, and Cu(p,x)Co monitor reactions. Calculated cross sections were compared against literature values and theoretical TALYS predictions. Notably this work includes the first reported independent cross section measurements of Cu(p,x)Co and Cu(p,x)Co.
铁、铜和铝叠层箔在洛斯阿拉莫斯中子科学中心的同位素生产设施中受到90兆电子伏特质子的辐照，以测量用于生产医学相关同位素（如锰、铬、钴和镍）的核截面。在辐照后的几个月里，使用高纯锗伽马能谱法监测辐照过程中产生的放射性同位素的衰变。质子注量通过铝（p，x）钠、铜（p，x）锌、铜（p，x）锌和铜（p，x）钴监测反应来确定。将计算出的截面与文献值和理论TALYS预测值进行比较。值得注意的是，这项工作包括首次报道的铜（p，x）钴和铜（p，x）钴独立截面测量。
