We have measured the scaled-energy absorption spectra of argon Rydberg states in a uniform electric field. The experiment utilized laser spectroscopy from the metastable 4s[3/2]2 state in a fast atom beam. The scaled absorption spectra are Fourier tr

We describe new techniques involving trapped atoms as targets for measurements of electron-impact ionization cross sections out of an excited level. By directly detecting the ions formed by electron collisions, we have obtained the first experimental

Using scaled-energy spectroscopy techniques (recurrence spectroscopy) we investigate the influence of collisionally induced decoherence on semiclassical orbits in the Stark-Rydberg system. This experimental investigation represents the first applicat

Experimentally obtained Stark-recurrence spectra taken at low principal quantum numbers show unusual degrees of orbit profile asymmetry. To clearly illustrate the semiclassical mechanisms behind this behavior a numerical experiment is performed where

We have measured cross sections for the electron-impact excitation out of the metastable levels of neon into the ten levels of the ${2p}^{5}3p$ configuration. Two sources of metastable neon atoms were used, a hollow-cathode discharge and a fast beam
