The recoil correction to the ground-state energy of hydrogenlike atoms is calculated to all orders in [Formula Presented] in the range [Formula Presented]–110. The nuclear size corrections to the recoil effect are partially taken into account. In the case of hydrogen, the relativistic recoil correction beyond the Salpeter contribution and the nonrelativistic nuclear size correction to the recoil effect amounts to [Formula Presented] kHz. The total recoil correction to the ground-state energy in hydrogenlike uranium [Formula Presented] constitutes 0.46 eV.
