Paper Abstract

Studies of the dipole polarizabilities in a broad frequency range were recently reported for rare-gas atoms, in which the polarizabilities have been calculated on the basis of the modern experimental data on the differential dipole oscillator strength distributions in the resonance absorption spectra of He, Ne, Ar, Kr and Xe atoms. The calculated dynamic polarizabilities (alpha) ((omega) ) are found to be in a good agreement with the available and most reliable experimental data, the deviations being within the stated error bounds of the latter (0.1 - 0.2%). Calculations have been performed in the spectral range from the static limit up to the frequencies of the second atomic resonance transitions. Convenient analytic approximations for the (alpha) ((omega) ) functions are proposed, that are of superior accuracy compared to the commonly used three-term formulas for the polarizability dispersion.
