Interference of First- and Second-Order Transitions in Resonant Photoemission

Аннотация

Resonant photoemission in narrow-band materials is characterized by the sum of first- and second- order transitions. Their quantum-mechanical interference results in enhancement of the valence-band spectrum and the emergence of an asymmetric dependence on the photon energy. These effects are studied theoretically and experimentally in intermetallic TbNi₂Mn compounds.
