Line Plot from Scientific Research

The solid lines show the cold reference spectra (absorption coefficient A ) whereas the dotted lines show spectra where the pre-edge features are prominent, as obtained at I = 5 x 10 13 W cm −2. The vertical dashed lines, labelled 3 d N , show the calculated 2 p 3/2 3 d N -> 3 d N +1 excitation energies of various ions (Supplementary Information Section VI.B ).
