On satellites hidden by diagram line in heavy elements Ir, Pt, Au

The hidden satellites due to Coster-Kronig transition especially have the characteristic threshold in their appearance. To clarify the hidden satellites, we measured Lβ2,3,15 spectra below and above the L1 edge on Ir, Pt, Au. The measured spectra were normalized using Lβ1 spectra. The hidden satellite were confirmed as the differences of two normalized spectra.
