Abstract

The absolute energies of the Lyman- $α$ lines of hydrogenlike iron have been measured with an accuracy of 90 ppm with use of a high-precision plane-crystal spectrometer calibrated directly with Co $K α$ x rays. A value for the $1 s$ Lamb shift of hydrogenlike iron has been deduced from this measurement.
