Saturated amplification on Xe(L) transition arrays at 2.9 angstroms from hollow atom states

Summary form only given, as follows. The findings presented experimentally demonstrate at λ∼2.9 Å the operation of a new concept capable of producing the ideal conditions for amplification of multikilovolt X-rays and prove the feasibility of a compact X-ray illuminator that can cost-efficiency achieve the mission of X-ray biological microholography and likewise serve an array of other applications involving the fabrication and measurement of solid state nanostructures.
