Abstract
The angular distribution of the photoelectron yield excited by two coherently related photon beams has been calculated and measured. Dynamical Bragg diffraction from a Ge(111) single crystal was used to generate the two beams, and L-shell photoelectron yields from an I overlayer were measured with a variable-angular-acceptance detector. The use of two-beam photoelectric excitation to understand final-state angular momentum symmetry is demonstrated.Keywords
