extended close-coupling method

extended close-coupling method

[ik¦stend·əd ‚klōs ′kəp·liŋ ‚meth·əd]
(atomic physics)
A method of extending the close-coupling method to the case of ionizing collisions of an electron with a hydrogen atom by replacing the true continuum of ionized hydrogenic target states with a finite number of discrete, normalized, positive-energy pseudostates, while treating the incident electron with conventional, two-body scattering boundary conditions.
