Abstract
The line positions and linewidths of photoelectron spectra arising from multiphoton ionization are analyzed for the first reported time in the subpicosecond (0.5–1.0-psec) region. Measurements performed with 248-nm radiation at intensity level for which the quiver energy of the free-electron motion is comparable with the photon energy are an reported. The short-pulse property causes the photoelectron energy to become a dynamical variable associated with the process of ionization and significantly influences both the line positions and the linewidths of the observed electron spectra.
