Abstract
We predict the recoil-induced molecular dissociation in hard-x-ray photoionization. The recoil effect is caused by electronic and photon momentum exchange with the molecule. We show the strong role ...

The dynamics and spectroscopy of highly excited states of molecules is an issue of great importance to chemical physics
In the case of the NO molecule the recoil-induced dissociation can be observed at the PETRA synchrotron using time-of-flight spectroscopy for dissociation ions as well by detecting the atomic peak in fluorescence
Our preliminary analysis shows that the effect can be observed in hard-x-ray F1s ionization of CF4, PF5, SF6, and MoF6 molecules
Summary
The dynamics and spectroscopy of highly excited states of molecules is an issue of great importance to chemical physics. The related recoil-induced vibrational and rotational excitations have received significant attention in x-ray photoelectron and Auger spectroscopies in the sub-keV x-ray energy range, where electronic recoil dominates and its role is rather weak. This generally justifies the use of the time-honored Franck-Condon (FC) principle in the soft-x-ray region where the momentum exchange between the photoelectron and molecules manifests itself as small rotational and translational Doppler broadenings as well as a small recoil shift of the vibrational resonances due to momentum transfer to the center-of-gravity (CG) of the molecule. This makes understanding x-ray spectroscopy in the energy range above 10 keV an ongoing challenge and very timely
