Description

In this experiment we use the stacked foil activation technique to measure cross sections for the ${}^{nat}$La(p,x) reaction, with proton energies in the 35-60 MeV range. The primary motivation for this measurement is to quantify the production of ${}^{134}$Ce, a positron-emitting analogue of the medical isotope ${}^{225}$Ac, which has applications for kinetic bio-distribution assays of new radio-pharmaceuticals. The results of this measurement show significant deviations from the cross sections modeled by the TALYS and EMPIRE nuclear reaction codes using default parameters. There are no previous measurements of this reaction for comparison.
