Fully differential cross sections for photo-double-ionization of D 2

Abstract

The four-body fragmentation of D2 molecule which was followed by single photon absorption was analyzed. The relaxation of one of selection rules valid for He photo-double-ionization and strong dependence of electron angular distribution on orientation of molecular axis were observed. The fully differential cross sections (FDCS) indicated that angular correlation pattern was formed by electron-electron correlation in final state. The model in which pair of photoionization amplitudes was also introduced for light polarization parallel and perpendicular to molecular axis. Show more
