The effect of the two-body charge and current densities is considered in the deuteron photoabsorption sum rules. The modifications induced in the Siegert form of the E1 operator give rise to an enhancement factor k/sub 2/approx. =0.2 over the Thomas-Reiche-Kuhn value of the integrated cross section sigma/sub 0/. The bremsstrahlung-weighted cross section sigma/sub -/1(E1) is found practically unchanged with respect to its value in impulse approximation, while sigma/sub -/1(M1) shows a 30% increase. The calculations are performed with hard-core, soft-core, and super-soft-core potentials. The dependence on the potential model is small for sigma/sub 0/ and quite negligible for sigma/sub -/1.
