摘要：

Ionization of D-2 launches a vibrational wave packet on the ground state of D-2(+). Removal of the second electron places a pair of D+ ions onto a Coulombic potential. Measuring the D+ kinetic energy determines the time delay between the first and the second ionization. Caught between a falling ionization and a rapidly rising intensity, the typical lifetime of the D-2(+) intermediate is less than 5 fs when an intense 8.6 fs laser pulse is used. We simulate Coulomb explosion imaging of the ground state wave function of D-2 by a 4 fs optical pulse and compare with our experimental observations.
