Abstract

Using an improved value for the energy splitting between the [formula] and [formula] states, electromagnetically induced transparency for x rays at the [formula] resonance in Ne is reassessed. The energy splitting between the [formula] and [formula] states is calculated with two independent approaches. In the first approach, first-order nonrelativistic many-body perturbation theory is employed. In the second approach, the Dirac-Fock method is combined with the relativistic configuration interaction method. Both approaches give an energy splitting of [formula]. The calculated x-ray absorption near-edge structure of laser-dressed Ne agrees closely with an earlier prediction. It may therefore be expected that at a laser intensity of [formula], the [formula] x-ray absorption cross section of Ne is suppressed by more than an order of magnitude.
