title: Relativistic linear response wave functions and dynamic scattering tensor for the ns1/2 states in hydrogenlike atoms.
abstract: We report a novel closed-form analytic representation for the linear response relativistic wave function of the hydrogenic ns(1/2) level that is exposed to dipole radiation of frequency omega. This result is derived by means of a direct analytical solution of the inhomogeneous omega-dependent Dirac equation. The utility of the formulas obtained is demonstrated by new analytic and numerical calculations of the static and dynamic relativistic dynamic polarizabilities of the lowest hydrogenic ns(1/2) states.
