RADIATIVE BHABHA SCATTERING AT DA-PHI-NE

The problem of computing radiative Bhabha scattering cross sections in the realistic experimental setup at DA Phi NE energies is considered. The matrix element for the reaction e(+)e(-) --> e(+)e(-)y at very small electron scattering angles is computed exactly and compared with existing results. Finite mass corrections are explicitly given for the very forward scattering region. A numerical study is presented for electron single tagging at very small angle, electron-positron double tagging both at small and large angles and electron-photon coincidence rates in the forward direction.
