Additional features in the 3d-4p x-ray-emission spectrum of Xe

• The high-resolution 3d-4p x-ray-emission spectrum of Xe excited by electron impact was measured. In addition to the prominent peak due to 3d5/2-4p3/2 previously reported, the experimental high-resolution spectrum shows a weak peak, identified as 3d3/2-4P3/2, and satellites. The satellites are tentatively attributed to 3d-1X-1-4p-1X-1 (X = 4s, 4p, and 4d), where the initial doubly ionized states are created by the Auger (Coster-Kronig) decay of the 2p and/or 3p level. The experimental 3d-4p x-ray spectrum is compared with a theoretical spectrum calculated by the ab initio Green's-function method.
