TY - THES AB - Method development of the time-dependent numerical MCSCF and CI method for atoms, without and with inclusion of an oscillating electric field, linearly polarized (electric dipole approximation for light). In the CI method, the numerical orbitals are kept fixed (not time-dependent), and only the CI coefficients are propagated, whereas in the MCSCF method both the CI coefficients and the numerical orbitals in the CSFs are propagated. The basis for this work were the non-relativistic numerical atomic structure codes for free atoms and for atoms in a static electric field developed at Bielefeld.
