Doppler-free Auger resonant Raman spectroscopy on photochemistry beamline at SPring-8.

A Doppler-free electron spectroscopy apparatus that consists of a high-resolution electron spectrometer and a molecular beam source has been installed on beamline 27SU at Spring-8 in Japan. The apparatus is described and the Auger resonant Raman spectra of neon atoms recorded at the 1s → 3p excitation and those of water molecules recorded at the O 1s → 2b[sub 2] excitation are presented to demonstrate the performance.
