Abstract: We present an angle resolved study of photoelectrons emitted from ions of the noble gases neon, argon and krypton by means of time-of-flight spectroscopy. The ionic targets are generated in a sequential two-photon process induced by the free-electron laser FLASH. Values of the anisotropy parametersandare derived from electron angular distribution measurements in the photon energy range from 38 to 91 eV and compared with recent theoretical calculations.
