Interference effects in photo-fragment distributions — •Kilian Hader and Volker Engel — Institut für Physikalische und Theoretische Chemie, Universität Würzburg, Am Hubland, 97074 Würzburg

Pronounced interference effects in the nuclear translational fragment distribution which are caused by the interaction with time-delayed femtosecond laser pulses have been predicted before [1]. Here, we extend the former studies and take the electronic motion explicitely into account. Dissociation, leading to different electronic states results in interesting features of the electron-nuclear wave-packet motion and fragment momentum-space distribution.
