“…Our work on electron wave packets in molecules [11][12][13] reveals a more complex picture. We have observed plateaus in plots of the period of motion of a molecular Rydberg wave packet as a function of the average principal quantum number in the superposition.…”

The dynamics of Rydberg wave packets in NO are investigated in the regime where the electronic period is comparable with the rotational motion of the molecular ion core. The presence of a rotating molecular core manifests itself in the wave packet dynamics as a series of peaks separated by the rotational beat period T Rot , but offset by ⌬T Rot , where ⌬ is the difference in quantum defect between the two dominant Rydberg series in the superposition. We rationalize this by treating the dynamics of a wave packet created from a coherent superposition of two interleaved Rydberg series as two separate electron wave packets, which interfere with one another when they overlap spatially. There is a periodic phase difference between the two wave packets that depends on the rotational energy of the core in each Rydberg series and also on the quantum defects. The resulting interference pattern in the Rydberg population manifests itself as peaks in the wave packet spectrum at the stroboscopic period.

“…We reported the first experimental observation of a Rydberg wave packet in a molecule just over three years ago. 23,24 Electron wave packets were created in NO using resonanceenhanced multiphoton excitation via a well-defined rotational level of the A-state, allowing some control over the core rotational angular momentum and the electronic orbital angular momentum of the Rydberg wave packet system. The A 2 S + state is the lowest Rydberg state (3ss) and its spectroscopy is very well characterised.…”

“…21,22 On the other hand, investigation of both electronic and nuclear motion in Rydberg molecules has only recently begun to receive attention. [23][24][25][26][27][28][29][30][31] Rydberg wave packets in small molecular systems exhibit many of the dynamical complications found in large ' chemical ' molecules, for example, the high density of rovibronic energy levels with combined non-adiabatic couplings and competing discrete-continuum interactions of various sorts. There are already excellent reviews of molecular Rydberg states, 32 and their importance in ZEKE spectroscopy.…”

Relative Phase Measurement of a Stark Wave Packet in the Vicinity of the Saddle Point

A gas of Rb atoms in a static electric field has been photoexcited to just above the classical ionization threshold by a phase-locked sequence of two far infrared pulses. A single laser pulse generates a series of ejected electron packets emerging at the saddle point of the potential; each of the ejected packets is characterized by a phase and a chirp. We calculate and measure these phases and chirps using the time dependent interference of the electronic wave function controlled by the delay between the two light pulses.
