Abstract

The atomic masses of the three most abundant isotopes of strontium, ^86,87,88Sr, and of the six most abundant isotopes of ytterbium, ^{170,171,172,173,174,176}Yb, have been obtained from measurements of cyclotron frequency ratios of pairs of ions simultaneously trapped in a Penning trap. Our results, with one standard deviation uncertainty, are M(⁸⁶Sr) = 85.909 260 730 9 (91) u, M(⁸⁷Sr) = 86.908 877 497 0 (91) u, M(⁸⁸Sr) = 87.905 612 257 1 (97) u, and M(¹⁷⁰Yb) = 169.934 767 241 (18) u, M(¹⁷¹Yb) = 170.936 331 514 (19) u, M(¹⁷²Yb) = 171.936 386 655 (18) u, M(¹⁷³Yb) = 172.938 216 213 (18) u, M(¹⁷⁴Yb) = 173.938 867 539 (18) u, M(¹⁷⁶Yb) = 175.942 574 702 (22) u. These results have application to photon-recoil determinations of the fine-structure constant.
