Abstract

Using an improved value for the energy splitting between the 1 s-1 3s S01 and 1 s-1 3p P11 states, electromagnetically induced transparency for x rays at the 1s→3p resonance in Ne is reassessed. The energy splitting between the 1 s-1 3s S01 and 1 s-1 3p P11 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 1.88 eV. 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 1013 W/ cm2, the 1s→3p x-ray absorption cross section of Ne is suppressed by more than an order of magnitude. © 2008 The American Physical Society.
