Continuum Random Phase Approximation based on Point Coupling RMF Lagrangian. — •Ioannis Daoutidis and Peter Ring — Physik-Department der Technischen Universität München, D-85748 Garching, Germany

Relativistic Continuum Random Phase Approximation (CRPA) is used to investigate collective excitation phenomena in several spherical nuclei along the periodic table. For the ground state, we perform point Coupling RMF calculations with the parameter set PC-F1. Using a residual interaction, derived from the same RMF approach, we solve the RPA equations in order to produce the isoscalar monopole, isovector dipole and isoscalar quadrupole resonances. Finally, we compare their properties, such as centroid energies and strengths, with those of the well studied discrete RPA approaches. Experimental data are also given for comparison.
