【 摘 要 】

We report measured cross sections for radionuclides produced via proton irradiation of stacked(nat) La foils at the Isotope Production Facility at Los Alamos National Laboratory. Incident proton energies of approximately 100 MeV were degraded to ten energy positions ranging from 88 MeV to 46 MeV. HPGe gamma spectrometry was used to quantify residuals at LANL and the University of Wisconsin-Madison. Of particular interest was the cross section of Ce-134 due to its potential as the imaging component of a theranostic pair with Ac-225. Theoretical values from TENDL (2017) proton libraries are compared with the experimental cross section measurements of Ce-134 and other radionuclides.
