Abstract: We analyze the contribution of the different terms of the nucleon-nucleon interaction to the nuclear symmetry energy S-0 and its slope parameter L by using the Hellmann-Feynman theorem. The analysis is done using the Argonne V18 potential plus the Urbana IX three-body force within the framework of the microscopic Brueckner-Hartree-Fock approach. Our results show that the potential part of the nuclear Hamiltonian, and in particular the tensor component of the nuclear force, gives the main contribution to both S-0 and L. The kinetic contribution to S-0 is very small and negative, in agreement with recent results.
