Abstract
The special features of magneto-dipole photoionization of
s-atomic states are analyzed and the possibilities of experimental
observation of this effect are discussed. It has been shown that despite the
smallness of total cross sections of magnetic processes as compared with
electric-dipole ones, the experimental observation of magnetic effects is
possible, in principle, if photoelectrons are registered in the directions
perpendicular to both the polarization vector of photon and its momentum;
i.e. in the directions where the differential cross section of
electric-dipole ionization of s-atomic states is close to zero. The
possibilities of the derived general formulas for the magneto-dipole cross
sections are illustrated by numerical calculations for s-subshells of He and
Be atoms.
