The isotope of bromine, 75Br (T1/2=1.6 h), has a considerable interest in nuclear medicine. The radionuclide 75Br is a positron emitter and is useful in positron emission tomography (PET) for fast metabolic processes. In this study the reaction cross sections were calculated for suggested various production mechanisms. The cross sections of charged particle-induced reactions, leading to 75Br, were calculated for 76Se(p,2n)75Br, 76Se(d,3n)75Br, 75As(3He,3n)75Br and 75As(4He,4n)75Br using TALYS 1.6. The calculated results are compared with measurement data available in literature. The calculated results indicate that, 76Se(p,2n)75Br and 76Se(d,3n)75Br reaction channels have higher cross section values than that of 75As(3He,3n)75Br reaction channel. Moreover all these reaction channels are in the range of a medium-sized cyclotron.
