Wirkungsquerschnitte und Winkelverteilungen von Photoelektronen bei der Photoionisation von Fullerenen

The slope of the partial cross sections of the valence photoionisation of the fullerenes C_6_0 and C_7_0 was measured in the gas phase in the range from hf=20 eV up to hf=125 eV. The cross sections of the highest molecule orbitals oscillate in dependence on the photon energy hf. It could be shown that the periodicity of the intensity oscillations for the condensed anf the gas phase agrees. The intensity oscillations of the C_7_0 cluster are less prenounciated in comparison to C_6_0, but their periodicity is nearly equal.SIGLEAvailable from: http://edocs.tu-berlin.de/diss/1998 / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekDEGerman
