Abstract The stochastic variational method is used in conjunction with stabilization ideas to compute the low energy phase shifts and scattering lengths for positronium-atom scattering. Results are obtained for the Ps-H, Ps-Li+, Ps-He, and Ps-Ps systems. The Ps-H scattering lengths are probably accurate to better than 5% and are the most accurate so far computed. The results for Ps-Li+ and Ps-Ps scattering represent the first published scattering lengths for these systems. The positive scattering length for completely spin-aligned (3)Ps-(3)Ps scattering, namely 2.95a(o), is particularly significant since it demonstrates the feasibility of forming a stable Bose-Einstein condensate of (3)Ps atoms.
