Calculation of Reaction Cross Sections for Producing Br-75 in the Energy Range of 5-40 MeV

The isotope of bromine, ⁷⁵Br ($T_{1/2}$ = 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
