The photodisintegration of deuterium at 0° for the outgoing protons

Abstract

The absolute differential cross section for the photodisintegration of the deuteron at 0° for the outgoing protons has been measured at lab photon energies of 20, 30, 40, 75, 100 and 120 MeV using a magnetic spectrometer and a bremsstrahlung beam. The absolute cross-section values have an error of ±6% and were determined with an angular resolution of 1.5°. A serious discrepancy is found to exist between the measured 0° cross sections and those predicted by calculations using the Hamada-Johnston and the boundary condition potential models.
