The QB method: analysing resonances using R-matrix theory. Applications to , He and Li
Lisa Quigley,Keith A. Berrington +1 more
TL;DR: In this paper, a procedure for analysing resonances in atomic and molecular collision theory is introduced, which exploits the analytic properties of R-matrix theory to obtain the energy derivative of the reactance matrix, without assuming a pure Coulomb potential at large distances.
