      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 ...

      Monoenergetic (e+e-) pairs from heavy ion collisions 

      Berdemann, E.; Bosch, F.; Kienle, P.; Koenig, W.; Kozhuharov, C.; Tsertos, Haralambos; Schuhbeck, S.; Huchler, S.; Kemmer, J.; Schröter, A. (1988)
      Energy and angular correlations of (e+e-) pairs emitted in HI collisions were investigated. Some evidence is found for a weak peak at 815±5keV in the (e+e-) sum-energy spectrum obtained for θe+c- = 180° ± 18° (FWHM). The ...
