Abstract

Femtosecond vacuum ultraviolet pulses from a monochromated high harmonic generation source excite vibrational wavepackets in the B1 Sg+ state of D2. The wavepacket motion is measured through strong field ionization into bound and dissociative ion states yielding D2+ and D+ products. The time depende...

Abstract: Femtosecond vacuum ultraviolet pulses from a monochromated high harmonic generation source excite vibrational wavepackets in the B1 Sg+ state of D2. The wavepacket motion is measured through strong field ionization into bound and dissociative ion states yielding D2+ and D+ products. The time dependence of the D2+ and D+ ion signals provides a sensitive fingerprint of the quantum nuclear wavepacket, due to the different ionization rates for the two channels. The experiments are modelled with excitation and ionization processes included explicitly, with the results of the model showing a very good agreement with the experimental observations. The experiment demonstrates the level of detail attainable when studying ultrafast quantum nuclear dynamics using high harmonic sources
