Temperature dependence of the dipole polarizability of xenon (1S0) due to dynamic non-resonant Stark effect caused by black-body radiation Original Research Article

The temperature dependence of the dipole polarizability α(ω, T) of ground state xenon has been measured in the ranges of temperature and wavelength between 293 and 1080 K and 633 and 325 nm, respectively. In this temperature range an increase of Δα/α ≈ 0.2%/1000 K has been detected, which increases slightly with the frequency ω of the measuring light. The temperature dependent change in α(ω, T) is attributed to the non-resonant Stark shift of the energy levels of xenon due to black-body radiation.
