The angular distribution of photoelectrons emitted from the K shell of lead and platinum by 483 keV linearly polarized photons has been studied. At forward emission angles the photoelectrons are emitted predominantly in the plane of polarization of the photons, but at an emission angle of 72 degrees a crossover effect is observed and the preferred plane of emission is orthogonal to the polarization plane of the photons. Although the crossover effect is expected from theoretical considerations it is observed to occur at a smaller emission angle than predicted by theory.
