| Abstract: | The interaction between Ps and a strong laser pulse of short duration is studied. Substantial population is deposited in excited states under few photon excitation. The possible usefulness as a source of excited Ps to spectroscopy and the formation of antihydrogen is discussed. Finally, photoelectron energy spectra are calculated. This revised version was published online in August 2006 with corrections to the Cover Date. |
| Keywords: | positronium strong field driving efficient excitation (above threshold) ionization |
