Second-order Doppler frequency shifts of trapped ions in a linear Paul trap
S. N. Miao, J. W. Zhang, Y. Zheng +5
The accurate evaluation of the second-order Doppler frequency shift (SODFS) of trapped ions in a linear Paul trap has been studied with experiments and molecular dynamics (MD) simu…
Determination of hyperfine splittings and Landé factors of and states of Cd for a microwave frequency standard
J. Z. Han, R. Si, H. R. Qin +6
Regarding trapped-ion microwave-frequency standards, we report on the determination of hyperfine splittings and Landé factors of Cd. The hyperfine splittings…
