    Abstract:
    We have made a measurement of very-low-energy e+e- pair production from p collisions at 18 GeV/c. Using the SLAC 1-m bubble chamber to study a sample of 178×103 interactions, we find a signal of centrally produced direct e+e- pairs which accounts for (4813)% of all e+e- pairs detected with |x|<0.02 and PT<10 MeV/c. This measurement agrees with a calculation of e+e- pair production from the internal conversion of hadronic bremsstrahlung. © 1981 The American Physical Society.
