✦ Synopsis

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 l/R6 and l/R7 found by Penfield and Zatskis (8)" 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 l/R*: the Penfield and Zatskis correction, valid at near distances only, is dominated by the static London l/R7 attraction.

The relativistic effects on the quantization of the harmonic oscillator are determined from a perturbation calculation using matrices obtained in the nonrelativistic case. One finds that the energy levels are no longer evenly spaced although the usual transition rules still hold. When a system of
