Abstract

The first measurement of photoelectron spectra emitted in the photoionization of a single-charged-ion beam by synchrotron radiation is reported. A ${Ca}^{+}$ -ion beam is resonantly photoionized by the monochromatized photon beam of the SU6 undulator of the SuperACO Storage Ring at 33.20 eV photon energy. The values observed for the kinetic energy and for the intensity of the photoelectron line are in good agreement with the predicted values. The success of this feasibility experiment opens up wide opportunities for similar photoionization and Auger studies on multiply charged ions.
