Surface Structure Determination with ARPEFS

Theory of angle-resolved photoemission extended fine structure

“…The first part which we will call the zeroth-order problem, contains all of the dynamical (timedependent) physics; the second part, the scattering problem, includes the scattering from ion cores as a perturbation on the zeroth-order wave ~ function. Thus w(r) is constructed in the scattering problem as (2) ~ using w 0 (r) from the zeroth-order problem, and we form…”
