H. Lefebvrebrion, INTENSITY ANOMALIES IN THE ZERO-ELECTRON-KINETIC ENERGY-SPECTRA OF MOLECULES IONIZING INTO (2)PI STATES, Chemical physics letters, 253(1-2), 1996, pp. 43-48
Intensity anomalies in the ZEKE-PFI spectra of molecules with a (2) Pi
ion core are explained from decay by rotational and spin-orbit autoio
nization. Calculations of this effect agree well with experimental res
ults obtained for CO2 and HCl.
