We investigate the single selectron production associated with photino ( e+e- → e+ ~γ~ eR- and e+e- → e+ ~γ~ eL- in longitudinally polarized e+e- beams, taking into account the real production processes which occur as the intermediate states at certain energies. We calculate the polarized cross sections for the ~ eR- production and for the ~ eL- production, the angular distributions and the energy distributions of the outgoing positron, and the angular distributions of ~ eR- and ~ eL- with polarized e+e- beams. It is shown that the information on the low-energy mass spectrum of supersymmetric particles may be obtained from the study of the polarized cross sections. The angular distributions with polarized e+e- beams are important to obtain the signature of the selectron production and the information of the low-energy mass spectrum.
