For total energies below the ionization threshold it is possible to dramatically reduce the computational

burden of the solution of the electron-atom scattering problem based on grid methods combined with

the exterior complex scaling. As in the R-matrix method, the problem can be split into the inner and outer

problem, where the outer problem considers only the energetically accessible asymptotic channels. The

(N+1)-electron inner problem is coupled to the one-electron outer problems for every channel, resulting

in a matrix that scales only linearly with size of the outer grid.
