    "abstract": "We present a theoretical formulation for the description of nuclear\nexcitations within the framework of relativistic random-phase approximation\nwhereby the vacuum polarization arising from nucleon-antinucleon fields is duly\naccounted for. The vacuum contribution to Lagrangian is explicitly described as\nextra new terms of interacting mesons by means of the derivative expansion of\nthe effective action. It is shown that the self-consistent calculation yields\nzero eigenvalue for the spurious isoscalar-dipole state and also conserves the\nvector-current density.",
