Inner-shell ionization of xenon 4d electrons have been studied by the binary (e,2e) spectroscopy at the impact energies of 1200, 1600, and 2400 eV. Experimental energy-momentum densities and the impact-energy dependence of momentum distributions of 4d{sub 5/2} and 4d{sub 3/2} are reported, the results are compared with the distorted-wave impulse approximation and the distorted-wave Born approximation. Moreover, the cross-section ratios of 4d{sub 5/2} to 4d{sub 3/2} are further provided at these different impact energies, which clearly manifest the relativistic effects. Some similarities and dissimilarities are observed on the impact-energy dependence of momentum distributions of 4d{sub 5/2} and 4d{sub 3/2} states and their cross-section ratios.
