Resonance signatures in the body-frame valence photoionization of CF4

We present a combined experimental and theoretical investigation of the electron dynamics and body-frame angular dependence of valence photo-single ionization of CF 4 and subsequent dissociation into CF 3 + and F. Ionization from a valence t 2 orbital shows overlapping shape resonances close to thre...

Description
Summary:We present a combined experimental and theoretical investigation of the electron dynamics and body-frame angular dependence of valence photo-single ionization of CF 4 and subsequent dissociation into CF 3 + and F. Ionization from a valence t 2 orbital shows overlapping shape resonances close to threshold that couple to the same total symmetry, leading to striking changes in the photoelectron angular distributions when viewed in the body-frame. Photoionization of the 4t 2 orbital of CF 4 shows overlapping resonances close to threshold, leading to a striking inversion of the photoelectron angular distribution when viewed in the body-frame.
