Isotope shifts in ?326.1 nm of CdI

Abstract

We have measured isotope shifts in λ326.1 nm of CdI using a pressure-scanned interferometer. The results are, in GHz: 116–106, −2.222 (30); 113–108, −1.052(10); 111–110, −0.049 (12); 111–106, −1.048 (10). Results for stable isotopes in λ326.1 nm are needed in the interpretation of existing measurements on radioactive cadmium isotopes. The new data are more precise than early atomic beam measurements but are reasonably consistent with them.
