Fig. 2

a Experimental diffraction-difference signal in momentum space (ΔsM) as a function of pump-probe delay. The orange box highlights the inelastic scattering signal and the purple dashed arrow indicates the position shift of the enhanced band at  ~ 2 Å−1. b, c The simulated ΔsM for ring-closing and ring-opening trajectories, respectively. The simulated results are convolved with a Gaussian function with 80-fs FWHM. Two panels share a single colorbar. d The integrated intensity of the inelastic signal. The fitting is described in the main text. e, f The experimental and simulated ΔsM at four selected time delays. The uncertainty represented by the shaded regions in (d and e) corresponds to a 68% confidence interval. Source data are provided as a Source Data file.
