Abstract
We present numerical ab initio calculations for a two-electron quantum system that is a one-dimensional analogue of the He atom in a strong laser field. Electron correlation occurring within this model can be treated exactly. We compare our calculations with a single-electron model that employs a proper effective potential for the `outer' electron. Evidence of fast correlated double ionization is presented and discussed.Keywords
