- Resonant soft x-ray emission spectroscopy has been applied to study the issue of symmetry breaking upon core-hole excitation in molecular oxygen. The results provide direct evidence that the inversion symmetry is not broken in the core-excited states. Furthermore, the experiments themselves demonstrate a new experimental technique of broad applicability for studies of electronic structure and excitation dynamics in free atoms and molecules.

- X-ray fluorescence of condensed C-60 has been recorded in high resolution using monochromatic synchrotron radiation excitation. Strong intensity modulation of constituent spectral features is observed with varying excitation energy up to 10 eV above threshold. The energy dependence is interpreted as due to resonant inelastic x-ray scattering, leading to symmetry selection rules governing the two-photon process in the fully symmetric molecule.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The surface core-level shift in C 1s soft x-ray photoemission spectroscopy has been experimentally observed in films of C-60 on Al. A value of 0.100+/-0.025 eV has been determined. Theoretical calculations are presented which show that the core hole is un
