Abstract
Full text: There has been much progress in the solution of the three-body problem that is electron-impact excitation of atomic hydrogen. Hence, the next frontier in the field is the four-body problem of electron-impact excitation of helium. Interestingly, since the helium discrete spectrum contains only one-electron excitations, a frozen-core description of the target suffices for discrete excitation phenomena and ionisation leaving the helium ion in the ground state. However, ionisation processes may also leave the helium ion in an excited state, and double ionisation processes are also possible. To treat these the full four-body problem needs to be solved. We will report the first attempts to solve this problem non-perturbatively while restricting all orbital angular momenta to be zero, the so-called S-wave model.
