摘要：

Spin-orbit (σ→•L→) terms of the heavy-quark potential are calculated taking into account the effect of instantons in the dilute-gas approximation. It is shown that these terms can be expressed by means of differential operators acting on a certain potential V which is not related to the spin-independent potential of Callan et al. A rough estimate of the terms is also presented. © 1979 The American Physical Society.
