    "abstract": "The structure of $^6$Li, $^7$Li and $^{11}$Li nuclei is investigated in a\nmodel space which includes all configurations with oscillator energy up to\n$3\\hbar\\omega$ above the ground state configuration. The energy spectra and\nelectromagnetic properties of the low-lying states are determined with various\ntwo-body interactions, which are derived from the Bonn potential. The results\nof these shell-model calculations depend on the strength of the tensor\ncomponent contained in the NN interaction and also on the treatment of the\nDirac spinors for the nucleons in the nuclear medium. In addition the\ncalculation determines the {\\it dipole polarizability} of $^7$Li and $^{11}$Li\ncaused from virtual $E1$ excitations to the positive parity states of these\nnuclei. It is demonstrated that the BAGEL scheme provides a very powerful tool\nto consider contributions from virtual excitations up to large energies.",
