摘要：

Forward-scattering peaks in the angular distribution of photoelectrons rotate for a dominant angular and magnetic quantum number pair L(0)=(l(0),m(0)) in the direct wave. This rotation is explained within the quantum-mechanical scattering theory. The result is an extension of the model of Daimon et al. [Jpn. J. Appl. Phys. 32, L1480 (1993)] who use a semiclassical picture of motion. An approximate formula is derived within the single-scattering approximation. It is shown that the phase of the scattering amplitude at forward scattering determines whether there is a maximum or a minimum in the intensity.
