Abstract : An experimental study was made to determine the nonpolarized ultraviolet reflectivity and characteristic electron energy loss spectra for ZnO and CdS and to correlate these data using a Kramers-Kronig dispersion relation. Reflectivity measurements were made using a 1-m Jarrell-Ash monochromator with low pressure capillary discharge source. Ruthemann-Lang type energy loss measurements were made using 10 keV transmitted electrons. All samples were single crystal platelets grown by the vapor phase technique. Correlation was made using a Fortran IV code developed for the IBM 7090 system. Repeatable spectra were obtained by both techniques, and preliminary correlation indicated good agreement between data.
