Chirped pulse ionization: bondlength dynamics and interference effects — •Volker Engel, Theo Lohmüller, and marco Erdmann — Institut für Physikalische Chemie, Universität Würzburg, Am Hubland, D-97074 Würzburg, Germany

Ionization with chirped pulses is studied using the Na₂ molecule as a numerical example. Bondlength expectation–values are determined for different linear chirp parameters. It is shown that under certain conditions the photoelectron spectra can exhibit a pronounced interference structure which has an analogy in oscillatory patterns and the rainbow structure found in the scattering amplitude for atom–atom collisions.
