    "abstract": "The general tensorial form of the orbit-orbit interaction operator in the\nformalism of second quantization is presented. Such an expression is needed to\ncalculate both diagonal and off-diagonal matrix elements with respect to\nconfigurations, in a uniform way. Some special cases are shown for which the\norbit-orbit interaction operator reduces to simple form. The importance of\ndifferent contributions to the Breit-Pauli hamiltonian is investigated in\nground states and ionization potentials for Li isoelectronic sequency in the\nsystematic way.",
