Abstract
Photon-induced fluorescence spectroscopy (PIFS) using monochromatized synchrotron radiation for exciting the sample selectively and a fluorescence spectrometer with a position-sensitive photon detector for recording its fluorescence spectrum is a very powerful experimental technique especially for the investigation of atomic and molecular photoionization and photodissociation. To reduce the contributions of higher harmonics of the undulator radiation which are also transmitted through the primary monochromator a very compact He absorber was developed. With a He pressure of 30 mbar in the differentially pumped gas cell of the absorber the fraction of the third harmonic of the undulator transmitted through the monochromator was reduced by a factor of 175 for an exciting-photon energy of the first order of 24.18 eV.
