A series of x-ray emission spectra of xenon in the region of L{sub 3}M{sub 5,4}(L{alpha}{sub 1,2}) and L{sub 3}N{sub 5,4}(L{beta}{sub 2,15}) lines were recorded along the polarization direction of the incoming photons with energies ranging from 4779.4 to 4804.4 eV. A combination of monochromatic photon beam and high resolution x-ray spectrometer resulted in the experimental broadening of 1 eV allowing the observation of resonantly enhanced and narrowed emission lines from the decay of [2p{sub 3/2}]nd,ns states. The measured spectra are decomposed into the continuum and resonant contributions to determine their relative emission strengths and the energies of the lowest resonant excitations converging to the L{sub 3} edge. The calculated differential cross section for inelastically scattered photons is compared to the measured data. Each of the resonant states is described by a single relativistic configuration in the frame of the Dirac-Fock model, and the continuum contribution to the scattered light is evaluated within the Caldwell-Zare approach, which neglects anisotropic interaction of the ejected electron with the ion.
