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.
