Angle-resolved Auger spectroscopy of K-shell ionized molecules

Synopsis We report on measured oxygen K-LL Auger spectra induced by 1.5-keV electron impact on O2, CO2, and N2O gaseous targets. An ESA-22-type electron spectrometer was employed which is capable of simultaneous energy and angular analysis covering a polar angular range of 15° to 345°. The measureme...

Description
Summary:Synopsis We report on measured oxygen K-LL Auger spectra induced by 1.5-keV electron impact on O2, CO2, and N2O gaseous targets. An ESA-22-type electron spectrometer was employed which is capable of simultaneous energy and angular analysis covering a polar angular range of 15° to 345°. The measurements were carried out in preparation for future experiments with more complex chiral molecular targets and a spin-polarized electron source. The present experimental data are compared with results from earlier experimental studies.
