The '''Axilrod–Teller potential''' is a three-body [[potential]] that results from a third-order perturbation correction to the attractive [[van der Waals force|London dispersion interactions]] (instantaneous induced dipole-induced dipole)

:<math>
V_{ijk}= E_{0} \left[
\frac{1 + 3 \cos\gamma_{i} \cos\gamma_{j} \cos\gamma_{k}}{\left( r_{ij} r_{jk} r_{ik} \right)^3}
\right]
</math>

where <math>r_{ij}</math> is the distance between atoms <math>i</math> and <math>j</math>, and <math>\gamma_{i}</math> is the angle between the vectors
<math>\mathbf{r}_{ij}</math> and <math>\mathbf{r}_{ik}</math>. The coefficient <math>E_{0}</math> is positive and of the order <math>V\alpha^{3}</math>, where <math>V</math> is the ionization energy and <math>\alpha</math> is the mean atomic polarizability; the exact value of <math>E_{0}</math> depends on the magnitudes of the dipole matrix elements and on the energies of the <math>p</math> orbitals.
