Abstract
Accurate -wave phase shifts for low-energy () positron-hydrogen scattering have been calculated by use of the finite-element method. Simple criteria are developed for which the truncation of the relevant configuration space and its subsequent discretization appear to be optimized. These criteria are expected to be independent of the details of the collision system.
