Abstract
Using an ion-photon merged-beam apparatus, photoion yield spectra of E u2+ and Eu3+ from the 4d photoionization of Eu+ were measured as a fun ction of photon energy in the range 110-160 eV. The measured spectra l ook very similar to those from a neutral Eu target. Both Eu2+ and Eu3 yield spectra, a broad 'giant resonance' appears at 140 eV with some preceding small peaks at 131.5, 132.8 and 134.7 eV. The summit of the 'giant resonance' in the Eu2+ spectrum is split into two peaks. This i s not observed in neutral Eu photoionization.
