Abstract

The two Auger electron emitting radionuclides of bromine, namely 77Br (T1/2=57.04 h) and 80mBr (T1/2=4.4 h), are promising candidates for internal radiotherapy. In this work, nuclear reaction cross sections were determined for their production using enriched Se targets. Thin Se samples were irradiated with incident protons of energies up to 85 MeV and the induced radioactivity was measured via non-destructive γ-ray spectroscopy, allowing the determination and extension of the excitation functions of the four reactions 77,78,80Se(pxn) 77Br and 80Se(pn)80mBr. The possible thick target yields were calculated and the different production routes discussed, especially with regard to the yield and the radionuclidic purity of the produced radionuclides.
