Differential cross section for the /sup 2/H(. gamma. ,p)n reaction between 100 and 255 MeV

Journal Article · · Phys. Rev. C; (United States)
Differential cross sections for the /sup 2/H(..gamma..,p)n reaction were measured at five laboratory angles from 32.5/sup 0/ to 130/sup 0/, for photon energies between 100 and 255 MeV, in 10 MeV steps. A quasi-monochromatic photon beam, obtained by positron in-flight annihilation on a liquid hydrogen radiator, was used, and the photon spectrum was measured on-line by a pair spectrometer. The normalization uncertainty is within +-5%. Data agree, within the total errors, with recent results of a tagged-photon experiment and of a measurement of the inverse process. The measured angular distributions were fitted by a sum of Legendre polynomials, and the results compared with recent calculations. Significant departures from the calculated angular distribution asymmetry have been found.
