Caption : mass-selected experimental tpes of sis (m/z 60 amu). the black trace shows the spectrum obtained when integrating over an electron kinetic energy between 0 and 20 mev and the blue trace between 70 and 90 mev. apart from the degradation in resolution observed and expected for faster photoelectrons, the differences between both spectra are attributed to autoionisation features.
