Abstract:
Multiple photoionization cross sections from the K shell are studied
for all levels of the Fe2+ 3d6 configuration. The study shows that
the quadruple photoionization leads to the largest cross sections. A
large variation in the multiple photoionization cross sections is
determined among the levels of the Fe2+ 3d6 configuration. Main
decay branches of radiative and Auger cascades, following the
photoionization of the K shell for the ground configuration of the
Fe2+ ion, are identified. The radiative and Auger cascade is studied
by considering transitions among energy levels and subconfigurations.
The obtained data for ion yields are compared with previous
calculations produced for configuration averages.
Description:
Multiple photoionization cross sections for the K shell of the Fe2+
ion are investigated. The radiative and Auger cascade is studied by
considering transitions among energy levels and subconfigurations.
