We present a low-energy expansion of the Kramers-Heisenberg formula for atomic hydrogen in terms of ω/ω 1 , where ω 1 and ω are the angular frequencies corresponding to the Lyman limit and the incident radiation, respectively. The leading term is proportional to (ω/ω 1 ) 4 , which admits a well-known classical interpretation. With higher-order terms, we achieve accuracy with errors less than 4 per cent of the scattering cross-sections in the region ω/ω 1 ≤ 0.6. In the neighbouring region around…

Exact low-energy expansion of the Rayleigh scattering cross-section by atomic hydrogen
We present an exact low-energy expansion redward of Lyα of the Rayleigh scattering cross-section by atomic hydrogen, which is given by the Kramers-Heisenberg formula. The expansion is expressed as a
