    "abstract": "The matrix equations of the random-phase approximation (RPA) are derived for\nthe point-coupling Lagrangian of the relativistic mean-field (RMF) model. Fully\nconsistent RMF plus (quasiparticle) RPA illustrative calculations of the\nisoscalar monopole, isovector dipole and isoscalar quadrupole response of\nspherical medium-heavy and heavy nuclei, test the phenomenological effective\ninteractions of the point-coupling RMF model. A comparison with experiment\nshows that the best point-coupling effective interactions accurately reproduce\nnot only ground-state properties, but also data on excitation energies of giant\nresonances.",
