Abstract
The differential elastic scattering cross sections of carbon, magnesium, aluminum, silicon, sulfur, copper, silver, tantalum, wolfram, lead, and bismuth for 340-Mev protons are measured as a function of the angle of scattering. The source of the 340-Mev protons is the external scattered deflected proton beam of the Berkeley 184-inch synchrocyclotron. The scattered protons are detected by a triple coincidence scintillation counter telescope whose detection threshold is set by copper energy attenuators placed between the last two transtilbene scintillators.
