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...
