Deuteron photodisintegration at intermediate energies

Differential cross sections for the /sup 2/H(γ,p)n reaction were measured at five laboratory angles, from 320 to 1300, for photon energies between 100 and 250 MeV. The LEALE quasi-monochromatic photon beam, obtained at Frascati by positron annihilation on liquid hydrogen target, was used; the photon beam spectrum was measured on-line by a pair spectrometer. Preliminary values of angular distributions and total cross sections at three laboratory photon energies are presented
