Abstract

Using Green’s functions and Hartree–Fock methods, we study resonances in double ionization of the Ne atom by one photon; they appear because of multielectron interactions. The obtained average delay times for satellite lines in the photoelectron spectrum are in agreement with experiments. It is established that the average delay times of the satellites in the photoelectron spectrum are related to the resonance width by a relation that is close to the resonance width–lifetime uncertainty relation.
