Project description.
Investigations of structure and dynamics of small molecules using synchrotron radiation. Applications to chemical physics, astrophysics, fusion research and environmental research.The group has constructed an experimental station which has been in use at the synchrotron facility MAX in Lund, where the decay of synchrotron light excited small molecules is studied using ion- and photon spectrometers and coincidence techniques. Photoionization and photodissocia tion of small fundamental molecules have been studied at valence shell energies as well as at inner shell energies using undulator radiation. Several new structures and resonances have been found, which are of importance for understanding various processes in nature where these molecules participate. Energy distributions of fragment ions from inner shell excitations have been extracted and a new kind of doubly excited molecular states have been found. A new technique for measuring sub-femtosecond lifetimes has been developed.
