A study of ($p$,$\mathrm{xn}$) and ($p$,$\mathrm{pxn}$) reactions on ${}_{}{}^{79}{}_{}{}^{}\mathrm{Br}$ and ${}_{}{}^{81}{}_{}{}^{}\mathrm{Br}$ was made. The excitation functions were measured in the energy range 10-85 MeV. The excitation functions experimentally obtained were compared with those predicted by intranuclear cascades and two pre-equilibrium models followed by equilibrium evaporation. None of the three computer codes was able to reproduce all excitation functions satisfactorily. The relative success of the computer codes tested is discussed.
