Abstract
A study has been made of the energy and angular distributions of the electrons produced when the x-ray beam from the 322-Mev Berkeley synchrotron falls on a slab of lead one-half inch in thickness. A cloud chamber containing the piece of lead was in a magnetic field of 1800 gauss. Measurements were made on 1286 electron secondaries having energies greater than three Mev. The energy and angular distributions of these electrons are in satisfactory agreement with the theory.
