Precise determination of the isotope shift of ${}^{88}$Sr - ${}^{87}$Sr optical lattice clock by sharing perturbations

Tetsushi Takano, Ray Mizushima, Hidetoshi Katori

We report on the isotope shift between ${}^{88}$Sr and ${}^{87}$Sr on the ${}^1{S}_0-{}^3{P}_0$ clock transitions. The interleaved operation of an optical lattice clock with two isot…
