Deuterons from the 42-inch cyclotron were scattered by a thin deuterium gas target. Scattered particles were detected by photographic emulsions in a nuclear multiplate camera. The differential cross section for elastic scattering was measured at 5° intervals in the center-of-mass system, from 25° to 145°, the estimated absolute rms standard error of the measured cross sections being ±3.1 percent. The measurements extend the angular range of the previous measurements of Allred, Erickson, Fowler, and Stovall at 10.8 Mev, and are in very good agreement with their values when the difference in bombarding energy is taken into account.
