Circular dichroism of angular distributions of photoelectrons emitted from heavy polarized alkali atoms

The angular distributions of photoelectrons, emitted from the ground state of polarized heavy alkali atoms, are predicted to depend on the helicity of the photon. The effect should occur, in the purely electric dipole approximation, for photon energies from the region of so-called nonzero minimum of the photoionization cross-section. Formulae are proposed for experimental determination of the frequency-dependence of Fano's parameter x. (author)
