| contents | We measured the spectral distribution of the absolute differential cross section of both ordinary and polarization ultra-soft X-ray bremsstrahlung for 0.7 keV electrons scattered on substrate-free nanoclusters of xenon. Clusters were produced in a supersonic gas jet expanding adiabatically into a vacuum. An original method based on absolute measurements of the intensity of the atom and cluster emission in the vacuum ultraviolet and ultra-soft X-ray spectral regions was used to determine the cluster density in the scattering area. The bremsstrahlung arising from scattering of electrons on clusters had a polarization component which dominated the differential cross section. For the first time, cluster size effect on the formation of the polarization bremsstrahlung was found for xenon. |
