The scattering of electrons by acoustic phonons in an InSb-like semiconductor has been shown previously to be influenced strongly by the symmetry of the electronic wave function near the conduction-band minimum. In this work we show how to extract values of the acoustic "deformation potentials" ${\epsilon }_0$, ${\epsilon }_1$, and ${\epsilon }_2$ from the self-consistent relativistic orthogonalized-plane-wave claculations for InSb and InAs. With their use one can compute the energy dependence of the electronic scattering.
