Production cross-sections of 181–186Re isotopes from proton bombardment of natural tungsten

Abstract

Cross-sections for the production of 181Re, 182mRe, 182gRe, 183Re, 184Re, and 186Re from proton bombardment of natural tungsten have been measured using the stacked foil technique for proton energies up to 17.6 MeV. Results are compared with the theoretical excitation functions as calculated by the EMPIRE II code (version 2.19) and experimental literature values. Results are in strong agreement with some of the previously reported literature as well at theoretical calculations for multiple reactions providing for more reliable estimates for the 186W(p, n) 186Re reaction.
