Abstract
A 24-in. diffusion cloud chamber filled with hydrogen and located in a magnetic field has been placed in the hardened bremsstrahlung beam of the Cornell synchrotron to study electron pair production in the proton field (P.F. pairs) and in the electron field (E.F. pairs). The E.F. pairs could be detected with an average efficiency of ∼85% and are about as abundant as the P.F. pairs. A total of 3065 pairs produced by photons with energy from 10 to 1040 Mev have been analyzed.Keywords
