It is shown that under certain conditions an instantaneous resolvent G z ; t of a time-dependent Kohn-Sham

or Kohn-Sham-Dirac operator H t can be defined from which the particle and the magnetization density can

be evaluated directly using contour integrations. The corresponding Greenīs function can be evaluated within

a multiple-scattering scheme by solving at each given time t coupled radial differential equations for the

single-site problem. This scheme is in particular intriguing since within the adiabatic time-dependent density

functional the configurational part of a time-dependent perturbation can be viewed as a contribution to an

effective full potential. First applications are shown for an Fe atom excited by a femtosecond laser pulse.\
