摘要：

Expressions for the angular distribution of photoelectrons from polarized atoms and for the magnetic dichroism in the angular distribution are obtained taking into account a full multipole expansion of radiation in electric and magnetic moments. Non-dipole effects in circular and linear magnetic dichroism in the angular distribution are analysed within the first-order corrections. An experimental arrangement is proposed to observe tire non-dipole effects in the magnetic dichroism in the angular distribution and, for the first time, calculations of these effects are performed. Pronounced non-dipole effects are predicted for the photoionization of the sodium atom in the 3p state in the region of the Cooper minimum at photon energies as low as 10 eV.
