Deciphering the electronic behavior of the ionised CO molecule

Auger spectroscopy and photoemission spectroscopy experiments carried out at SPring8 and SOLEIL help deciphering the electronic behavior of the ionised CO molecule. The results, published in New Journal of Physics by scientists from Swedish, Japanese, German and French laboratories, show that such analyses will now make possible to study highly excited states of molecular ions which overlap with features from normal Auger spectra and which have not yet been observed with photoelectron spectroscopy directly.
