  title = {Ionization of H(1s) by laser pulses: a close-coupling study},
  abstract = {<p>Here we present one of the first complete treatments of the ionization of a real atom by realistic laser pulses of arbitrary length and intensity. A large basis set of hydrogenic bound and discretized continuum states is employed in a close-coupling solution of the full time-dependent Schrödinger equation to give converged results for the resulting ionization probability for H(1s). Various laser frequencies, corresponding to one- and three-photon ionization and the 1s-2p resonance, as well as laser intensities in the multi-photon, tunnelling and over-the-barrier ionization regimes are examined. It is seen that the ionization probability of H(1s) following a laser pulse is a very complicated function of frequency, phase, pulse shape, pulse length and intensity.</p>
