Abstract
The dynamical tensor polarizability in the ground state of hydrogen is calculated. It arises in the third order of perturbation theory with respect to operators of hyperfine and electric dipole interaction. The obtained analytical expression is a sum of linear and squared combinations of Gauss hypergeometric functions 2 F 1 . It is pointed out that the double refraction effect can be observed in polarized atomic hydrogen.
