Experimental K-edge NEXAFS near edge X-ray absorption fine structure data for solid Ne are compared with theoretical results. Seven features in the experimental spectrum that are not reproduced by the theoretical results are found to be attributable to two-electron excitations. Five of them are usual one-center excitations, but the remaining two are found to be novel two-center excitations involving resonant orbitals as opposed to the usual bound orbitals. In contrast, two-center, two-electron excitations involving only bound orbitals are found to be absent in the experimental spectrum. Rare gases, X-Ray absorption, NEXAFS.
