Abstract
We demonstrate that laser cooling, combined with -scheme optical double-resonance spectroscopy, provides a sensitive means to measure isotope shifts and hyperfine splittings. Our technique is illustrated using the 398.8-nm and 555.6-nm transitions in a neutral ytterbium atomic beam having natural isotopic composition. With a precision comparable to existing approaches, our unique method has enabled the most complete single-technique survey to date of the isotope shifts and hyperfine splittings.
