Scalar nature of the nuclear density functional

Abstract : We prove the existence theorem for a scalar density functional (DF) for nuclei. The theorem is a direct consequence of the rotational invariance of the nuclear Hamiltonian. Since the DF depends only on scalar densities, practical predictions of ground state (g.s.) energies reduce to one-dimensional, radial calculations
