Abstract

This chapter presents results from several experiments where electronic and vibrational wavepackets created by multiphoton excitation are resolved by outgoing electron energies and angular distributions. In all cases, the dynamics are treated in greater detail due to the detection method of photoelectron spectroscopy. In one example, a superposition of excited electronic states in krypton atoms is created. By measuring the time-resolved photoelectron spectrum, beat frequencies are extracted due to the states that are coherently populated. These results demonstrate the ability to employ strong pump laser fields to significantly perturb the electronic states, creating well-defined coherent superpositions that persist after the strong field pulse is finished. The selectivity of this method is verified in the Fourier transformation of the time-dependent signal and shows that the beat frequencies are well resolved.
