Abstract
For a semiinfinite medium and for a slab it is shown how the final state functions describing photoemission and field emission are to be defined if more than one solution of the Schrödinger equation for a fixed value of the energyE and the parallel componentk ∥ of the wave vectork exist. As by-product some interesting statements concerning complexband structure and the solutions of the Schrödinger equation for a semiinfinite medium or a crystalline slab are derived.
