Observation of coherence transfer by electron-electron correlation

We present the results of exact wave-function calculations that are equivalent to numerical experiments on a two-electron quantum system. We show that Rabi oscillations of the core electron can modify the photoelectron spectrum of the outer electron by efficient coherence transfer via e-e correlation, even in the absence of an autoionizing level or other continuum structure. We compare a simplified analytically soluble two-electron theory with our numerical results.
