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 52gMn, 54Mn, 48Cr, 55Co, 58mCo and 57Ni. 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 natAl(p,x)22Na, natCu(p,x)62Zn natCu(p,x)65Zn, and natCu(p,x)56Co 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 natCu(p,x)58mCo and natCu(p,x)58gCo.

质子诱导的铁，铜和铝的反应（Ep = 35-90 MeV）的核激发函数。

在洛斯阿拉莫斯中子科学中心的同位素生产设施中，用90 MeV质子辐照铁，铜和铝堆叠的箔，以测量用于生产医学相关同位素（例如52gMn，54Mn，48Cr，55Co，58mCo和57Ni）的核截面。 。在辐照后的几个月内，使用高纯锗γ光谱仪监测辐照过程中产生的放射性同位素的衰减。使用natAl（p，x）22Na，natCu（p，x）62Zn natCu（p，x）65Zn和natCu（p，x）56Co监测器反应确定质子通量。将计算出的横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告的natCu（p，x）58mCo和natCu（p，x）58gCo的独立截面测量。
