摘要: A method is proposed to solve a longstanding problem in photoelectron spectroscopy: the determination of branching ratio between intrinsic and extrinsic plasmon generation. Attosecond metrology combination with model simulations allow for disentanglement these excitation channels providing novel insight into many-electron response metals.
