      abstract     = {For the production of the medically interesting
                      radionuclides 76Br and 77Br cross sections of α-particle
                      induced reactions on arsenic, leading to the formation of
                      76,77,78Br as well as to the non-isotopic impurity 74As,
                      were measured from their thresholds up to 37 MeV. Sediments
                      of elemental arsenic were used as targets and irradiated,
                      using the established stacked-foil technique. In order to
                      remove discrepancies of the existing literature data, the
                      cross section ratios of the monitor nuclides 67Ga/66Ga were
                      used for determination of the α-particle energies as well
                      as the effective beam current through all the stacks, thus
                      inferring the experimental cross sections. Compared with the
                      available excitation functions the new data indicate
                      slightly divergent curve shapes. In the case of 76Br the
                      excitation function seems to be shifted to somewhat lower
                      α-particle energies, and also the maximum cross section of
                      the formation of 77Br tends to be slightly lower compared
                      with the curve recommended to date. In the case of a
                      re-evaluation, these new data should be taken into account,
                      as they may contribute to enhance the accuracy of the
                      excitation functions},
