Excitation functions of proton induced nuclear reactions on natSe leading to the formation of the radionuclides 82,80m,77,76,75Br, 75,73Se and 77.76, 72,71 As were measured from their respective thresholds up to 62 MeV. The selenium targets were prepared by vacuum deposition onto thin Al-backings. For the cross section measurements the conventional stacked-foil technique was used. Irradiations were performed at the AVF 930 cyclotron of the National Institute of Radiological Sciences in Chiba, Japan. Our results were compared with the available data in the literature, and some of the literature data obtained using isotopically enriched targets were used to validate our data. The experimental data sets generally showed good agreement. Integral yields of 75Br, 76Br, 77Br, 80mBr and 82Br were derived from the measured cross section data. The yield of 80mBr is quite high but, due to associated radionuclidic impurities, it is not meaningful to produce 80mBr using natSe as target material.
