Abstract

The atomic masses of S32, Kr 84,86, and Xe 129,132 have been measured by comparing cyclotron frequencies of single ions in a Penning trap. The results (with one standard deviation uncertainties) are M (S32)=31.972 071 173 5 (16), M (Kr84)=83.911 497 770 5 (50), M (Kr86) =85.910 610 672 2(84), M(Xe129)=128.904 780 960 (10), and M (Xe132) =131.904 155 190 7 (92). Combining our mass of S32 with the high-precision mass difference between S+33 and S32 H+ obtained by Rainville [submitted to Nature], we also obtain M(S33)=32.971 458 908 7 (16). These results are more precise than previous data by factors of 13 to 600.
