    "abstract": "The quantum vacuum in a many-body system of finite nuclei has been\ninvestigated within the relativistic Hartree approach which describes the bound\nstates of nucleons and anti-nucleons consistently. The contributions of the\nDirac sea to the source terms of the meson-field equations are taken into\naccount up to the one-nucleon loop and one-meson loop. The tensor couplings for\nthe $\\omega$- and $\\rho$-meson are included in the model. The overall nucleon\nspectra of shell-model states are in agreement with the data. The calculated\nanti-nucleon spectra in the vacuum differ about 20 -- 30 MeV with and without\nthe tensor-coupling effects.",
