This talk summarizes the results of our microscopic approach to study short-pulse ionization in a many atom system. The interaction of a highly off-resonant light pulse with an atomic gas is modeled fully microscopically. The theory systematically includes the light-atom interaction, as well as the electron-electron and electron-ion interaction effects on the distributions and the optically induced coherent polarization. The resulting equations are solved numerically for an atomic model system excited by a strong light pulse.

For pt.I see ibid., vol.17, p.1675 (1984). A theory of stepwise excitation of atoms is presented in which electron excitation is followed by strong single-mode laser excitation. A model of the strong laser excitation processes is considered and theoretical expressions are obtained for line polarizations and electron-photon coincidence signals applicable to both axial and planar symmetry stepwise excitation experiments.
