November 30 - Classical modeling of single and double ionization of atoms by lasers: the importance of the e‑e interaction
Students K. Shomsky, N. Danks, and Professor S. Haan
For several years our group has been using classical mechanics to study double ionization of atoms by strong lasers. It's agreed by now that the ionization is driven by "recolllision" in which one electron ionizes but returns and shares energy with the other electron. In this talk we consider what happens after recollision ‑‑ Do the electrons continue to interact as they drift out to the detector? Also, if one electron is left behind in an excited atomic state, can it absorb some additional energy from the laser and escape?
