Ultra-bright ultraviolet and soft X-ray beams produced at the Advanced
Light Source are achieving world records in spectroscopic resolution.
High-resolution spectroscopy in the 20 to 300 eV photon energy range
has been applied to photoionization yield and photoemission measuremen
ts in atoms and molecules to reveal previously unseen resonance series
in doubly-excited autoionizing states of helium, to analyze angular d
istributions in photoemission from doubly-excited states of helium and
other rare gases, to reveal vibrational and ligand-field splitting of
small molecules through photoionization, and, to examine photoemissio
n from doubly- and triply-excited hollow lithium atomic states.
