Abstract
Isotope shift spectroscopy with narrow optical transitions provides a benchmark for atomic struc- ture calculations, and has also been proposed as a way to constrain theories predicting physics beyond the Standard model. Here, we have measured frequency shifts of the 1S0 to 3P1 and 1S0 to 3P0 transitions between all stable isotopes of strontium relative to 88Sr. This includes the first reported measurements of the 1S0 to 3P0 isotope shift of 88Sr-86Sr and 88Sr-84Sr. Using the isotope shift measurements of the two transitions, a King plot analysis is performed. These results, combined with other recent isotope shifts measurements in other atomic systems will help place constraints on atomic structure calculations and theoretical predictions.
