We discuss the production of photinos in e⁺e^-→γ ̃ \~γ ̃ \~γ for arbitrary photino and scalar-electron masses. We present detailed cross sections as a function of various parameters, as well as a discussion of the background coming from e⁺e^-→γνν. We conclude from our analysis that it may be possible to observe the signatures of supersymmetry in this process only for scalar-electron and photino masses up to 40 and 5 GeV, respectively, and for √s40 GeV. Otherwise the process e⁺e^-→γνν becomes a dominant process.
