The integrated and bremsstrahlung-weighted cross section for deuteron photodisintegration have been calculated taking the relativistic one-body charge density and the two-body charge density with its local and nonlocal contributions for several nucleon-nucleon potentials in pseudoscalar and pseudovector pion-nucleon couplings. The relativistic correction lowers the enhancement factor for the soft-core potentials and raises it for the hard-core potentials as well as for the Paris potential which has velocity dependence in it to simulate the effect of the hard core. This increase and decrease pattern of the enhancement factor is found to be related to the maxima of the deuteron ground-state wave functions. Though there are some changes in the enhancement factor for different potentials, they are not large enough to enable us to distinguish between the various hard-core or soft-core nucleon-nucleon potentials.
