Relativistic time-dependent density functional calculations for the excited states of the cadmium dimer — •Ossama Kullie — Institute de Chimie de Strasbourg, CNRS et Universit'e de Strasbourg, Laboratoire de Chimie Quantique, Strasbourg, France. — Theoretical Physics, Department of Mathematics and Natural Science, University of Kassel, Germany. kullie@uni-kassel.de

In this poster we present a study for the ground-state as well the 20-lowest laying excited states of the cadmium dimer Cd2. The result is obtained from all electrons calculations performed with time-depended density functional for the relativistic Dirac-Coulomb- and relativistic spin-free-Hamiltonian as implemented in DIRAC-PACKAGE. The result shows that only long-range corrected functionals such as CAMB3LYP, gives the correct asymptotic behavior for the higher states. Spin-free-Hamiltonian is shown to be very efficient for systems containing heavy elements such as Cd2 in frameworks of (time-dependent) density functional without introducing large errors.
