Total-ion-yield X-ray absorption spectra of (a) N2 gas at the N K-edge (Ehν ≈ 401 eV) and (b) Ne gas at the Ne K-edge (Ehν ≈ 867 eV). The grating used to measure the spectra was 600 lines mm−1 (G600). The opening of the exit slit was 10 µm. The energy resolving power (Ehν/ΔE) was estimated to be ∼8700 at the N K-edge and ∼10500 at the Ne K-edge from the FWHM of the Gaussian in the peak fitting using Voigt functions: (a) N2 K-edge, FWHM of Gaussian and Lorentzian were 38 and 114 meV; (b) Ne K-edge, FWHM of Gaussian and Lorentzian were 100 and 240 meV, respectively. The solid circles and solid line represent the raw experimental data and the result of peak fitting, respectively. |
