Popis: A detailed discussion of the relativistic corrections to the van der Waals force is given for a simple model in which the neutral atoms are replaced by two linear oscillators orientated along the line of centers. The repulsive corrections proportional to 1/ R 6 and 1/ R 7 found by Penfield and Zatskis ( 8 ) 2 are considered in conjunction with the complete corrections obtained by Casimir and Polder ( 4 ) in a realistic model. It is shown that in the limit of electrodynamic interest, that is, separations large compared with the wavelength corresponding to the harmonic oscillator frequency, the total force is attractive and proportional to 1/Re: the Penfield and Zatskis correction, valid at near distances only, is dominated by the static London 1/R' attraction.
