Research output: Contribution to journalArticlepeer-review


The production of positron-electron pairs in collisions of [Formula Presented] at 5.95 MeV/nucleon, and of [Formula Presented] at 5.95, 6.1, and 6.3 MeV/nucleon, has been studied with the APEX spectrometer at Argonne National Laboratory. Several analyses have been performed to search for sharp structures in sum-energy spectra for positron-electron pairs. Such features have been reported in previous experiments. No statistically convincing evidence for such behavior is observed in the present data.
