K-Shell ionization of molecules:
Molecules investigated so far are: CO, N2, C2H2, C2H4, C2H6.
A compilation of movies showing the angular distribution of K-shell electrons from fixed in space CO and N2:
These experiments are performed by the COLTRIMS collaboration at ALS
Upper panel: Oxygen-K-shell, lower panel: Carbon-K-shell. The electron energy is 10eV in both cases. The direction of the molecule is indicated in the figure, the red dot symobilzes the Oxygene. The polarization is horizontal. The full line shows a fit of spherical harmonics up to l=4.
