Abstract
Non-zero width and Coulomb rescattering effects are analyzed for the pair production of smuons and selectrons near the thresholds in e+e- and e-e- collisions, respectively. The excitation curves are predicted in a gauge-invariant form. Energy cuts are designed to reduce irreducible supersymmetric backgrounds.
