Abstract
A puzzling feature is pointed out in the measurement of resonant photoemission by Lapayre and Anderson [Phys. Rev. Lett. 35 (1975) 117] as to the strong dependence of the emission intensity on the polarization of exciting light. A qualitative explanation is proposed by combining (a) the calculated angular distribution of emission, whose anisotropy is polarization dependent, (b) the refraction of photoelectrons at the surface, and (c) the effect of partial angle integration.
