DETERMINATION OF POLARIZATION OF VACUUM-ULTRAVIOLET RADIATION BY FLUORESCENCE AND PROBE-BEAM TECHNIQUES

Polarization analysis of vacuum ultraviolet (VUV) radiation, especiall y the analysis of elliptical polarization is of considerable scientifi c interest in many areas of physics including solar physics. Polarizat ion measurements in the VUV region are much less developed than those in visible and infrared spectral regions. It is due to lack of efficie nt phase shifting elements and small reflection coefficients of polari zers for VUV radiation. We propose two techniques, to determine the ar bitrary polarization of VUV radiation with photon energies in the rang e 10 - 100 eV, which seem to be more efficient and precise than the kn own techniques, especially to study the polarization of atomic or mole cular spectral lines.
