Project description.
Investigations of structure and dynamics of small molecules using synchrotron radiation. Appli
cations 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.
