| 抄録 | The laser cooling of ions confined in the radio-frequency (RF) ion trap is capable of providing ideal samples for experiment in very high-resolution spectroscopy. All even isotopes of Zn(+) ions have been laser-cooled in a linear RF ion trap, and isotope shifts in the 4s 2S(sub 1/2)-4p 2P(sub 3/2) transition were measured. Tunable continuous-wave coherent light near 202 nm was generated for this experiment by frequency conversion of light from solid-state lasers. The mass and the field shifts were estimated using a King plot. The results are useful for a future experiment to measure the frequency of the ground-state hyperfine splitting of Zn(+) ions precisely. |
