Abstract

The index of refraction and Verdet constant of atomic helium are calculated with the Padé approximant method from the first two oscillator strengths and the numerical values of α+(ν) which are connected with the dynamic polarizability α(ν) through the relation α(ν) = α+(ν) + α+(−ν). The results are compared with the experimental as well as the theoretical and semiempirical values.
