Abstract.

We have laser-cooled all even isotopes of Zn+ ions confined in a linear radio-frequency ion trap, and measuredoptical isotope shifts in the 4s 2 S 1/2-4p 2 P 3/2 transition. Tunable continuous-wave coherent light near 202 nm was generated for this experiment by means of frequency conversion of light from diode and solid-state lasers. The measured isotope shifts are as follows: 66Zn+-64Zn+, 0.676(6) GHz; 68Zn+-66Zn+, 0.670(4) GHz; and 70Zn+-68Zn+, 0.568(10) GHz. In all cases, the transition line of the heavier isotope was observed at the higher frequency. The mass and the field shifts were estimated using a King plot. This is the first isotope-shift measurement in the transition involving the ground (4s 2 S 1/2) state of Zn+ ions.
