Constant photoelectron energy (CPE) spectra of acetylene are reported for electron kinetic energies of 0, 0.1, 0.5, and 1.0 eV in the spectral range 11≤hν≤22 eV. This form of photoelectron spectroscopy involves measuring the intensity of photoelectrons with a particular kinetic energy as a function of the wavelength of the incident radiation. Such measurements may be carried out using small wavelength increments and can distinguish between direct and indirect, e.g., autoionization and photoionization processes. Autoionization features in the range 12.5≤hν≤16 eV are observed, which populate high vibrational levels of the ground state far beyond the Franck--Condon region.
