The method has been applied for the measurement of the 1 s Lamb shift in hydrogen-like gold (Au +78 ) in a storage ring through spectroscopy of the Lyman x-rays. This measurement represents the first result obtained for a high- Z element using high-resolution wavelength-dispersive spectroscopy in the hard x-ray regime, paving the way for sensitivity to higher-order QED effects.}, note = {Zweitver{\"o}ffentlichung}, issn = {1367-2630}, doi = {10.1088/1367-2630/aad01d}, url = {https://www.db-thueringen.de/receive/dbt_mods_00058153}, url = {http://uri.gbv.de/document/gvk:ppn:265510562}, url = {https://doi.org/10.1088/1367-2630/aad01d}, file = {:https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00060921/njp_20_7_073033.pdf:PDF}, language = {en} }
