Nuclear mass corrections to the Casimir-Polder interaction

We present a derivation of the finite nuclear mass corrections to the Casimir-Polder interaction between two atomic systems in the ground state. Equivalently, we show how the long-range asymptotics of the adiabatic correction is modified due to the finite speed of light. We show that in addition to the contribution resulting from the finite-mass correction to atomic polarizabilities, a further contribution exists.
