【 摘 要 】

In this work we report absolute cross section studies of prebiotic molecules measured in the VUV range using the double ion chamber technique and synchrotron radiation. Absorption, ionization and neutral decay cross sections will be presented, together with the absolute ionization quantum yield. Additionally, partial ion yield spectra were measured by a TOF mass spectrometer.
