Abstract
We report on the measurement of the thermal neutron capture cross section by , using as a benchmark for the development of our protocol, which implies the combination of two precise techniques: neutron activation in a nuclear research reactor and accelerator mass spectrometry (AMS). Beryllium oxide (BeO), graphite, and uracil () samples were irradiated at the TRIGA MARK III nuclear research reactor facility at Instituto Nacional de Investigaciones Nucleares (ININ), México. Later on, isotopic concentrations were quantified by AMS at Laboratorio de Espectrometría de Masas con Aceleradores (LEMA) of the Instituto de Física, Universidad Nacional Autónoma de México (IF-UNAM), Mexico. Cross sections for the and nuclear reactions were extracted for thermal neutrons.
