Evaluation of excitation functions of proton, 3He- and α-particle induced reactions for production of the medically interesting positron-emitter bromine-76

Cross section data for production of the medically interesting radionuclide 76Br ( T 1/2=16.2 h) via the proton induced reactions on 76Se, 77Se, 78Se and 79Br, and 3He- and α-particle induced reactions on 75As were evaluated. The nuclear model codes STAPRE, EMPIRE and TALYS were used to check the consistency in the experimental data and a statistical procedure was applied to derive the recommended excitation functions. A comparison of various production routes of 76Br (and of 75Br) is presented. ► First systematic treatment of production data of the novel positron emitter bromine-76. ► Nuclear model calculations using the codes STAPRE, EMPIRE and TALYS. ► Evaluation of data via statistical treatment, supported by nuclear model calculations. ► Detailed comparisons of various production routes of bromine-76 and bromine-75.
