【 摘 要 】

Electron emission provides an excellent opportunity to probe the electronic structure and the chemical reactivity of materials. For molecules, the most natural way is describing it in the molecular frame. Recently, using the upgraded version of the EPICEA coincidence setup available at PLEIADES beamline at SOLEIL (France), we were able to measure the electron emission in the molecular frame for kinetic energies up to several hundreds of eV. At these high energies the de Broglie wavelength is comparable to or smaller than the inter-nuclear distance, the possibility of observing the intramolecular electron diffraction thus being opened.
