      New results on e+e--line emission in U+Ta collisions ORANGE collaboration at GSI 

      Leinberger, U.; Berdermann, E.; Heine, F.; Heinz, S.; Joeres, O.; Kienle, P.; Koenig, I.; Koenig, W.; Kozhuharov, C.; Rhein, M.; Schröter, A.; Tsertos, Haralambos (1997)
      We present new results obtained from a series of follow-up e+e--coincidence measurements in heavy-ion collisions, utilizing an improved experimental set-up at the double-Orange β-spectrometer of GSI. The collision system ...

      Positron spectra from internal pair conversion observed in 238U + 181Ta collisions 

      Heinz, S.; Berdermann, E.; Heine, F.; Joeres, O.; Kienle, P.; Koenig, I.; Koenig, W.; Kozhuharov, C.; Leinberger, U.; Rhein, M.; Schröter, A.; Tsertos, Haralambos (2000)
      We present new results from measurements and simulations of positron spectra, originating from 238U + 181Ta collisions at beam energies close to the Coulomb barrier. The measurements were performed using an improved ...

      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 ...
