Abstract
The differential and total cross sections for the photodisintegration of the deuteron are calculated for incident gamma-ray energies in the range from 6 to 28 Mev. The following cases are treated: (1) Approximation I, in which shape-independent wave functions are used corresponding to a 50 percent charge-exchange central force, (2) Approximation II-C, in which a central Hulthén potential with a variable percentage of charge exchange forces is used, (3) Approximation II-NC, in which approximate noncentral Hulthén wave functions and an approximate noncentral Hulthén potential with 50 percent charge-exchange force, is used. In all these calculations, use is made (where possible) of a form for the interaction between the deuteron and radiation that gives the results of the interaction to all multipole orders automatically. We also estimate the possible effect of exchange currents on the cross section by a calculation making use of the phenomenologically derived exchange moments of Berger and Foldy.
