Abstract  This paper evaluates the interaction potential between a hydrogen and an antihydrogen using the second-order perturbation theory within the framework of the four-body system in a separable two-body basis. It finds that the H--$\bar{\rm H}$ interaction potential possesses the peculiar features of a shallow local minimum located around interatomic separations of $r\sim 6$\,a.u. and a barrier rising at $r\lesssim5 $\,a.u.
Keywords:  H--$\bar{\rm H}$ interaction      few-body problems      potential energy curve      perturbation theory
