Theoretical determination of polarizability and magnetic susceptibility of neon

摘要: We report theoretical determination of the dipole polarizability neon atom, including its frequency dependence. Corrections for relativistic, quantum electrodynamics, finite nuclear mass, and size effects are taken into account. obtain value ${\ensuremath{\alpha}}_{0}=2.66080(36)$ static polarizability, ${\ensuremath{\alpha}}_{2}=2.850(7)$ ${\ensuremath{\alpha}}_{4}=4.932(14)$ first two dispersion coefficients (Cauchy moments); all values in atomic units (a.u.). In case our result agrees with best experimental determination, Gaiser et al. [Phys. Rev. Lett. 120, 123203 (2018)], but estimated uncertainty is significantly larger. For coefficients, results obtained this work appear to be most accurate date overall compared published data. also calculated magnetic susceptibility needed refractive index gaseous neon. Our result, ${\ensuremath{\chi}}_{0}=\ensuremath{-}8.484(19)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ a.u., about 9% larger absolute than recommended value, Rumble [CRC Handbook Chemistry Physics (CRC Press, Boca Raton, FL, 2019)].
