The problem of including rigorously the Hartree-Fock exchange potential in the orthogonalized-plane-wave method is considered. Exchange bielectronic integrals are conveniently evaluated analytically by means of the Dawson auxiliary function, upon expansion of Slater-type orbitals into Gaussian-type orbitals. As an example of our procedure, we compute the Hartree-Fock energy bands of solid lithium hydride. The results are compared with earlier calculations and with the energy bands of the other isoelectronic compounds.
