Revision with unchanged content. Highly accurate probing techniques aid in understanding complex atomic electron systems. Some examples of complex atomic electron systems include multi-electron atoms, molecules, and atomic electrons in external electric fields. The techniques of scaled-energy recurrence spectroscopy, a Fourier transform method, are used in this dissertation to study the dynamics of highly-excited two-electron atoms created in a static electric field. In other experiments discussed here, ultra-short pulses of terahertz radiation, so called half-cycle pulses, are used to ionize ...
Revision with unchanged content. Highly accurate probing techniques aid in understanding complex atomic electron systems. Some examples of complex atomic electron systems include multi-electron atoms, molecules, and atomic electrons in external electric fields. The techniques of scaled-energy recurrence spectroscopy, a Fourier transform method, are used in this dissertation to study the dynamics of highly-excited two-electron atoms created in a static electric field. In other experiments discussed here, ultra-short pulses of terahertz radiation, so called half-cycle pulses, are used to ionize highly-excited Stark eigenstates, probing their electronic probability distributions in momentum space. Through these studies the characteristics of Stark states, ultra-short pulsed terahertz radiation, and the limitations and accuracy of these probing techniques are explored.
