199^Hg＋光频标的黑体辐射频移
Blackbody-radiation shift in a 199^Hg＋ ion optical frequency standard
摘要
Abstract
The background blackbody radiation causes the shift of the hyperfine energy level and affects the accuracy of the optical frequency standard. The polarizabilities of the hyperfine energy levels 5d^106s^2S1/2 （F = 0） and 5d^96s^2 2^D5/2 （F = 2） of 199Hg＋ are evaluated and the relative frequency shift at room temperature due to blackboby radiation is calculated to be -5.4 x 10^-17. Finally the effect of blackbody radiation on single 199^Hg＋ optical frequency standard is discussed at an ultralow temperature.关键词
