Experimentally investigated nuclear reactions for production of no-carrier-added Br-77 and Kr-77 were critically surveyed. The survey covered nine reactions for the formation of Br-77 and six reactions for Kr-77. Both radionuclides are simultaneously produced in many of the studied nuclear processes. The experimental data were compared with the results of nuclear model calculations based on the computer code ALICE-IPPE and the third version of TALYS-based Evaluated Nuclear Data Library, TENDL-2010. Good agreement was found over extended energy regions for the p-, He-3- and alpha-particle induced reactions on several target materials. In case of d-induced reactions, however, considerable discrepancies were noted between the experimental and theoretical data. The concordant sets of experimental cross section data for each reaction were fitted by a polynomial function to obtain a trend curve. From the thus obtained trend curves the yields of both Br-77 and Kr-77 were calculated. A discussion of suitable production routes is given.
