A spectroscopic study of the cycling transition 4s[3/2]{sub 2}-4p[5/2]{sub 3} at 811.8 nm in {sup 39}Ar : hyperfine structure and isotope shift.
- Physics
Doppler-free saturated absorption spectroscopy is performed on an enriched radioactive {sup 39}Ar sample. The spectrum of the 3s{sup 2}3p{sup 5}4s[3/2]{sub 2}-3s{sup 2}3p{sup 5}4p[5/2]{sub 3} cycling transition at 811.8 nm is recorded, and its isotope shift between {sup 39}Ar and {sup 40}Ar is derived. The hyperfine coupling constants A and B for both the 4s[3/2]{sub 2} and 4p[5/2]{sub 3} energy levels in {sup 39}Ar are also determined. The results partially disagree with a recently published measurement of the same transition. Based on earlier measurements as well as the current work, the isotope shift and hyperfine structure of the corresponding transition in {sup 37}Ar are also calculated. These spectroscopic data are essential for the realization of laser trapping and cooling of {sup 37,39}Ar.
