Abstract
R-matrix with time-dependence theory is applied to electron-impact ionisation processes for He
in the S-wave model. Cross sections for electron-impact excitation, ionisation and ionisation with
excitation for impact energies between 25 and 225 eV are in excellent agreement with benchmark
cross sections. Ultra-fast dynamics induced by a scattering event is observed through time-dependent
signatures associated with autoionisation from doubly excited states. Further insight into dynamics
can be obtained through examination of the spin components of the time-dependent wavefunction.
