LETTER TO THE EDITOR: Hollow-atom - hollow-ion decay routes of triply excited lithium: first Auger results and a comparison with <B> R</B>-matrix calculations
Abstract
We present the first photoelectron results for hollow-atom - hollow-ion decay paths of triply excited lithium, in which the hollow lithium atoms 0953-4075/30/18/002/img21 decay via hollow 0953-4075/30/18/002/img22 and then to 0953-4075/30/18/002/img23 ions. The high-resolution data, obtained at the 9.01 beamline of the Advanced Light Source at Berkeley, provide considerable insight into the decay pattern of the various hollow lithium resonances. Tracking the secondary 0953-4075/30/18/002/img24 Auger decays as functions of the incident photon energy provides new data on triply excited resonances. The results compare favourably with recent advanced R-matrix calculations. Detection of the individual 0953-4075/30/18/002/img24 Auger decay lines also provides information on the energies and widths of a number of doubly excited levels of the ion.
