• 論文の詳細を見る

• Analytic features of the spectra due to excitation of a core electron in metal with an incomplete shell are studied with a simple model. The incomplete shell (denoted by d state, representatively) is treated as a nondegenerate is assumed that in the initial state of the absorption the unoccupied d level is well above the Fermi energy ε_F while in the final states the d level of the excited atom is lowered down to ε_d due to the core hole left behind. When ε_d>ε_F, the singular absorption edge appears at ε_F as expected, with an antiresonance around ε^^-_d. When ε_d>ε_F, the singular absorption edge appears at ε^^-_d, the Fermi level threshold being blurred out by the life effect of the d hole. Emission spectra are also calculated. The results are compared qualitatively with experimental data.
