Abstract

The Ti Kα′′ satellite was investigated using a Johann-type spectrometer at the BL15XU undulator beam line, SPring-8. Ti Kα spectra were measured varying the excitation energy between 4996eV and 10000eV. The relative intensity of the Ti Kα′′ satellite to that of the Kα1,2 abruptly increases from 0% to 1.2% within 10eV around 5010eV. This indicates that shake-up process is likely to be concerned with creation of a 3p spectator hole which induces the Kα′′ satellite. Onset energy of the satellite appearance experimentally determined is 5005eV, and this value corresponds to the [1s3p] double ionization threshold energy in Z+1 approximation. The experimental results of this work confirm that the origin of the Kα′′ satellite is a 3p spectator hole as predicted by Scott theoretically.
