      Sensitive search for neutral resonances in Bhabha scattering around 1.8 MeV/c2 

      Tsertos, Haralambos; Kozhuharov, C.; Armbruster, P.; Kienle, P.; Krusche, B.; Schreckenbach, K. (1988)
      The excitation function for Bhabha scattering was measured in the energy range between 760 and 840 keV (CM) in 1.4 keV steps with beams of monochromatic positrons scattered on a Be foil at angles between 79° and 101° (CM). ...

      Systematic studies of positron production in heavy-ion collisions near the Coulomb barrier 

      Tsertos, Haralambos; Berdermann, E.; Bosch, F.; Clemente, M.; Huchler, S.; Kienle, P.; Koenig, W.; Kozhuharov, C. (1992)
      We present the results obtained from systematic studies of positron creation for a series of heavy-collision systems, with united charge Zu=Z1+Z2 ranging from Zu=164 (Pb + Pb) to Zu=184 (U+U) at bombarding energies close ...

      Weak e+e- lines from internal pair conversion observed in collisions of 238U with heavy nuclei 

      Heinz, S.; Berdermann, E.; Heine, F.; Joeres, O.; Kienle, P.; Koenig, I.; Koenig, W.; Kozhuharov, C.; Leinberger, U.; Rhein, M.; Schröter, A.; Tsertos, Haralambos (1998)
      We present the results of a Doppler-shift correction to the measured e+e--sum-energy spectra obtained from e+e--coincidence measurements in 238U + 206Pb and 238U + 181Ta collisions at beam energies close to the Coulomb ...
