| 内容記述 | We theoretically investigate the influence of electron-hole pair excitations on Kα X-ray emission spectroscopy (XES) in 3d transition metals (TMs) from Cr to Cu. Utilizing Keldysh Green’s function method for nonequilibrium states, we calculated the Kα XES spectra for nonmagnetic and (anti)ferromagnetic 3d TMs. We applied the lowest-order Born and local random-phase approximations to incorporate the effects of electron-hole pair excitations on XES spectral shapes. Our results reveal that electron-hole bound states notably modify the Kα XES spectral profiles of 3d TMs. Moreover, shoulder and satellite peaks appear on the low-energy side of the Kα peaks for Cr, Mn, and Fe.Considering these bound states, we can obtain a trend in the asymmetry index that aligns well with experimental findings. This study shows that accurately predicting Kα XES for 3d TMs requires detailed treatment of the magnetic state and 3d electron-hole pair excitations. | |||||||||
