Definitive results for elastic positron-hydrogen collisions are obtained using the Schwinger variational principle in the momentum space at low and intermediate energies corresponding to momenta in the range k{sub i}=0-3.5 atomic units. The discrete basis set used in the calculation makes allowance for long-range dipole polarization, atomic distortion, and infinite-order short-range positron-electron correlation. Results for the scattering parameters, such as the scattering length, phase shifts for all significant partial waves, and total cross section, are in conformity with other accurate variational and nonvariational calculations available in the literature.
