摘要: Ultrafast proton migration in 1,3-butadiene an intense laser field (40 fs, 4.5 × 1014 W cm−2) is investigated by using Coulomb explosion coincidence momentum imaging. The spatial distribution maps of a migrating reconstructed for the two three-body pathways, C4H63+ → H+ + CH3+ C3H2+ and C2H+ C2H4+, reveal that protons migrate within molecule, prior to three body decomposition.
