      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 ...

      On the momentum correlation of (e+e-) pairs observed in U + U and U + Pb collisions 

      Koenig, W.; Berdermann, E.; Bosch, F.; Huchler, S.; Kienle, P.; Kozhuharov, C.; Schröter, A.; Schuhbeck, S.; Tsertos, Haralambos (1989)
      First results on the energy and angular dependence of the (e+e-) pairs, emitted from U + U and U + Pb collisions at a beam energy of 5.9 MeV/u, are presented. The (e+e-) coincidence measurements were carried out utilizing ...
