Abstract
SynopsisWe investigate the post-collision interaction between a slow electron released by a pump pulse from the neutral helium atom and a fast electron released by a time-delayed probe pulse from the created ion. To this end, we numerically solve the time-dependent Schrödinger equation in the basis of the essential eigenstates of the unperturbed Hamiltonian. We demonstrate that the energy exchange between the slow and the fast electrons and the recapture of slow photoelectrons can be controlled by the properties of the pulse-sequence.
