(contribution withdrawn) Operator representation for realistic effective interactions — •Dennis Weber, Hans Feldmeier, and Thomas Neff — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany

We present a method to derive an operator representation for realistic effective interactions obtained in the ’Unitary Correlation Operator Method’ (UCOM) and ’Similarity Renormalization Group’ (SRG) approach starting from partial wave matrix-elements. This method allows to use interactions formulated in a partial wave basis in models which require an operator representation of the interaction. Furthermore it is possible to use this technique to derive interactions using a reduced set of operators for potentials with a known operator representation. To show that two-nucleon properties (scattering phase-shifts and Deuteron) and binding energies of light nuclei are the same for the initial partial wave matrix-elements and the derived operator representation, we compare the results of two-nucleon and ’No Core Shell Model’ calculations using the initial interaction matrix-elements and calculations with the obtained operator representation.
