The R-Matrix Method

The R-matrix method is reviewed both in the L2 and R-matrix propagation implementation. Results are presented for a simple elastic scattering problem showing the improvement in convergence when nonorthogonal L2 bases are used. Comparably accurate results are obtained with either non-orthogonal sine functions or a distributed Gaussian basis. The implications of these results, together with R-matrix propagation, for reactive scattering are discussed.
