Abstract: The cross section for the process e+e-→γγ has been measured for c.m. energies 39.561 GeV and Λ+> GeV (95% confidence level) have been determined. A search for two photon final states with missing energy provided lower limits on the masses of the photino and selectron. © 1984 Springer-Verlag.
