[Auszug] The index of refraction due to hydrogen atoms at frequency v0 is given by: n = 1 + 47TWV where is the Ladenburg for the transition, 3-8 x 10~12. The factor 1/4 appears because only the atoms in the lower state cause a phase shift. Summing over all hydrogen atoms: When T-〉0 this integral ...
