The atomic masses of the three most abundant isotopes of strontium, Sr-86,Sr-87,Sr-88, and of the six most abundant isotopes of ytterbium, Yb-170,Yb-171,Yb-172,Yb-173,Yb-174,Yb-176, 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(Sr-86) = 85.909 260 730 9 (91) u, M(Sr-87) = 86.908 877 497 0 (91) u, M(Sr-88) = 87.905 612 257 1 (97) u, and M(Yb-170) = 169.934 767 241 (18) u, M(Yb-171) = 170.936 331 514 (19) u, M(Yb-172) = 171.936 386 655 (18) u, M(Yb-173) = 172.938 216 213 (18) u, M(Yb-174) = 173.938 867 539 (18) u, M(Yb-176) = 175.942 574 702 (22) u. These results have application to photon-recoil determinations of the fine-structure constant.
