Time-dependent simulations of the single and double ionization of atomic Calcium using a two-active-electron model were performed. These simulations were implemented within a basis set representation, allowing for an unambiguous calculation of the single- and double-ionization probabilities. Thus, the electron wave packet dynamics have revealed the main feature responsible for the enhancement of double ionization which was observed in a recent adaptive control experiment. The simulations show that the initial part of the pulse prepares a coherent superposition of excited states above the first ionization threshold.
