Abstract

Spectra of resonance transition X-rays (RTR) generated in a periodical target composed of 9 Sn foils 11 μm in thickness spaced by 52 μm have been measured. They are shown to be significantly narrowed due to the influence of the K-shell photoabsorption edge. The ratio between intensities of RTR and bremsstrahlung is discussed. In the X-ray spectra measured using an equivalent continuous 100 μm Sn target the density effect is masked by the contribution of the transition radiation generated on the two surfaces.
