English A series of x-ray emission spectra of xenon in the region of L₃M _5,4(Lα_1,2) and L₃N_5,4 (Lβ_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_3/2]n d,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 L₃ 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.
