Abstract
A novel closed-form analytic representation for the linear response relativistic wave function of the hydrogenic ns 1/2 level that is exposed to a uniform dipole radiation of frequency ω is reported. This result is derived using a relativistic version of the PodolskySternheimerDalgarnoLewis method, that is, by means of direct analytical solving of the appropriate inhomogeneous ω-dependent Dirac equation, thus requiring no prior knowledge of the relativistic Coulomb Green's function. The utility of the formulas obtained for numerous potential applications is illustrated by new results of analytic and numerical calculations of the relativistic dipole dynamic polarizabilities of the 1s1/2 and 2s1/2 levels in hydrogen-like atoms.
