Abstract
Band-structure calculations are performed to assess the magnitude of relativistic effects in angle-resolved photoemission. The specific case of normal emission from Ag(111) is considered using a combined interpolation scheme which incorporates spin-orbit coupling both within the bands and between the plane waves of the basis set. Detailed numerical results are presented for the momentum matrix elements in the nonrelativistic and relativistic cases for all the initial-state bands in both parallel and perpendicular polarization. The observability of relativistic effects in available and future experimental data is discussed.
