Phys. Rev. Lett. 91, 093001 (2003) [4 pages]Relativistic Linear Response Wave Functions and Dynamic Scattering Tensor for the ns1/2 States in Hydrogenlike AtomsReceived 23 April 2003; published 27 August 2003 We report a novel closed-form analytic representation for the linear response relativistic wave function of the hydrogenic ns1/2 level that is exposed to dipole radiation of frequency ω. This result is derived by means of a direct analytical solution of the inhomogeneous ω-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 ns1/2 states. © 2003 The American Physical Society URL:
