(a) Δμ(Ε, t) at the Zn K-edge interpolated using Gouraud-type shading. Black-shaded regions indicate the temporal and energy profiles shown in (b) and (c). (b) Time evolution of the difference signal at 9661 e; the full line is the kinetic fit described in the main text. (c) The full absorption spectrum (gray line) and averaged spectral shape of Δμ(Ε, t) at t = 1.5–3 ps.
