N2 - By confining pairs of ions in a Penning trap, and alternating each ion between large and small cyclotron orbits, we have measured the cyclotron frequency ratios CD3+12 / O+18, C212 D6+ / O2+18, C3+12 / O2+18, CD3+13 / F+19, and Si28 H3+ / C12 F+19. Combined with other measurements for H, D, C13, and Si28, these ratios yield the atomic masses M (O18) =17.999 159 613 0(13) u, and M (F19) =18.998 403 162 9(11) u, which improve on previous values in the Atomic Mass Evaluation (AME2003) by factors of 500 and 60, respectively. Our value for M (O18) is lower than the AME2003 value by 1.4 (7) μu.
