We study isomeric effects using time resolved photoelectron circular dichroism (PECD). By a (1+1’)pump-probe ionisation with photoelectron collected by velocity map imaging technique, we compare relaxation dynamics from the 3s-Rydberg...

Velocity Mismatch

We show theoretically and by simulations how coherent transition radiation from tilted surfaces can be used for characterization of attosecond free-electron pulses such as used for pump-probe electron microscopy and diffraction. The tilted geometries eliminate velocity-mismatch and beam-diameter effects, providing sensitivity to attosecond times even for almost arbitrarily large beam diameters.
