“…This effect has already been identified as a drawback in comparison to ion trapping methods. 6,15,42 Figure 2 compares the mass spectra from the ion source of both the merged beam and ion trap setup at SOLEIL.…”

“…This kind of source, optimized for the production of multiply charged atomic ions, is known to produce ions in highly excited states. This effect has already been identified as a drawback in comparison to ion trapping methods. ,, Figure compares the mass spectra from the ion source of both the merged beam and ion trap setup at SOLEIL.…”

“…Since its discovery, Buckminsterfullerene and its ions have attracted much interest especially for their spectroscopic applications. − However, determination of spectroscopic properties of ions is difficult experimentally and consequently usually derived from theoretical calculations. Most of the knowledge of ion photoionizaton has been obtained using the so-called merged beam technique. − This method is based on the spatial overlap of a high-energy ion beam with a beam of probe particles such as electrons or photons. It was mainly applied to study atomic spectroscopy and has also allowed photoelectron spectra of ions to be measured. − Late, use of ion trapping techniques appeared as a complementary tool for atomic and cluster photoionization spectroscopy. , Although some measurements of the attenuation of the probe photon beam through stored ions have been reported, most of the trapping techniques rely on action spectroscopy.…”
