摘要：

We describe a recently developed B-spline R-matrix method for electron and photon collisions with atoms and ions. Using non-orthogonal sets of orbitals to construct the target description and to represent the scattering functions, this implementation of the close-coupling approach allows us to employ highly correlated target wavefunctions with relatively small configuration expansions. Example results from recent applications of the method for accurate calculations of low-energy electron scattering from He, Zn, Ne, At, Xe, and Fe+ are presented.
