The Δ Resonance Response Function in Charge-Changing Weak Interactions — •Andreas Fedoseew and Horst Lenske — Institut für Theoretische Physik, Justus-Liebig-Universität Giessen, Heinrich-Buff-Ring 16, D-35392 Giessen

We investigate the response of charge-changing excitations in nuclei in the Δ-resonance region. The N-N, Δ-N and Δ-Δ correlations are treated within the RPA framework. In our approach nuclear density functional theory is used for the self-consistent description of the ground state of nuclear matter and excitations. We include the self-energies in the baryon-propagators and calculate the residual p-h interaction self-consistently by applying Landaus Fermi-Liquid theory. With this approach our fully quantum mechanical calculations of the response functions are free of additional adjustable model parameters. We present our results for inclusive neutrino scattering on nuclei at the valley of stability and with high neutron excess.
