Abstract

Using single ions in a cryogenic Penning trap we have remeasured the atomic masses of Kr84,86 and Xe129,132 with the results M[Kr84]=83.911 497 731(8) u, M[Kr86]=85.910 610 628(8) u, M[Xe129]=128.904 780 859(11) u, and M[Xe132]=131.904 155 086(10) u. These results supersede those previously reported by Shi, Redshaw, and Myers [Phys. Rev A 72, 022510 (2005)], which suffered from systematic error associated with the comparison of heavy multicharged ions with singly charged reference ions.
