For a variety of reasons the scattering problem is technically a much more difficult problem to solve than the bound state problem. We have developed various approaches to solving low energy elastic scattering problems based on bound state calculations. The underlying idea is to solve the bound state problem to generate a wave function in the interaction region, then try and extract the phase shifts from the wave function or the discrete energies. Some of the applications include, positronium scattering and annihilation from atoms, positron scattering from atoms and the first identification of a shape resonance in the spectrum of any positron-atom system, superaccurate calculations of electron scattering from hydrogen and helium, positron scattering from the H2 molecule. One recent technical development is the development of the confined variational method (CVM). The CVM is well adapted to use with the stochastic variational method and recently provided the first description of the positron-H2 system with a completely unrestricted treatment of the strong electron-positron correlations that have made this a very difficult treatment to treat.
