By analyzing lab frame coherent rotational wavepacket evolution in a reaction microscope experiment [1] we measure the angle- and channel-resolved ionization and electron rescattering probabilities in the asymmetric-top molecule 1,3-butadiene. With this approach we achieve both polar and azimuthal angle-resolved molecular frame information, in contrast to previous works [2,3].
Our results indicate that the nodal structure of the ionizing orbitals is more strongly reflected in the electron rescattering probability rather than in the ionization probability. The molecular frame electron rescattering probability is significantly influenced by structured, channel-specific continuum electron wavepackets. Experimental results are compared with results from a TD-RIS [4] ab-initio simulation.
