Discrete variable representations and sudden models in quantum scattering theory. Lill, J. V., Parker, G. A., & Light, J. C. Chemical Physics Letters, 89(6):483–489, 1982.
doi  abstract   bibtex   
An exact formalism in which the scattering problem may be described by sets of coupled equations labeled either by basis functions or quadrature points is presented. Use of each frame and the simply evaluated unitary transformation which connects them results in an efficient procedure for performing quantum scattering calculations. Two approximations are compared with the IOS. \textcopyright 1982.
