RADIATIVE SCATTERING OF NEUTRALINO DARK MATTER

We investigate scattering between a photino and a nucleus accompanied by direct photon emission. We find that, as in the case of nuclear excitation with delayed gamma emission, the cross sections are too small for practical applications. We also look at the interactions between high-energy cosmic radiation and photinos in the halo. Lastly we examine the possibility of detection of collisions between high-energy electrons and dark-matter photinos in electron accelerators.
