      Investigations of correlated ρ+ e- emission in heavy-ion collisions near the Coulomb barrier 

      Koenig, I.; Berdermann, E.; Bosch, F.; Kienle, P.; Koenig, W.; Kozhuharov, C.; Schröter, A.; Tsertos, Haralambos (1993)
      We present the results obtained from a series of ρ+ρ--coincidence measurements in heavy-ion collisions using the double-Orange β-spectrometer at GSI. The collision systems U+U, U+Pb, and U+Ta were investigated at bombarding ...

      Positron lines from subcritical heavy ion-atom collisions 

      Koenig, W.; Bosch, F.; Kienle, P.; Kozhuharov, C.; Tsertos, Haralambos; Berdermann, E.; Huchler, S.; Wagner, W. (1987)
      Positron lines were observed in heavy ion-atom collisions at bombarding energies close to the Coulomb barrier in subcritical systems with the sum of the atomic numbers of the colliding nuclei Zu=Z1+Z2 being smaller than ...

      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 ...
