%X The convergence of the sums arising in the calculation of the electrostatic field gradient in crystals is discussed. In the point charge model of ionic crystals convergence ensues for any boundary shape, and not only for spheres. The method outlined is applied to Cu2O and NaClO3, and agreement obtained with previous work. The advantages of this method of computation are outlined.
