title: Analytically solving the relativistic Dirac-Coulomb equation for atoms and molecules.
abstract: A method of solving the Schrödinger equation in an analytically expanded form reported previously is extended to the relativistic case and a general method of exactly solving the Dirac-Coulomb equation has been proposed for atoms and molecules. Some problems characteristic of the relativistic case are discussed. Test applications to the hydrogen-like, helium-like atoms are satisfactory, implying a high potentiality of the proposed method also for the relativistic case.
