Gas phase TEY XAS spectra used to determine the beamline resolution. (a) He 1s2 → (2spn ± 2pns) double excitation. (b) Ar L2,3-edge of Ar. (c) N K-edge of N2. (d) O K-edge of O2. (e) Ne K-edge of Ne. All spectra were obtained with the 600 l mm−1 grating and the smallest vertical exit slit opening of 4 µm. |
