摘要：

The mass difference, m1H2O+ -m2HO+ = 0.001 548296(12), corresponding to a mass-ratio precision of 6 x 10(-10), has been determined by Fourier-transform ion-cyclotron-resonance (FT ICR) mass spectrometry. Three related results are calculated from that mass difference: 2m1H -m2H = 0.001 548 302(12) u; mass of the deuterium atom, 2.014 101 764(13) u; and deuteron binding energy, S(n)(H-2) = 2 388 183(14) nu [ = 2 224 579(13) eV, in which 1 u = 931.494 32(28) MeV]. In all three cases, the FT ICR mass-spectrometry-derived value improves significantly the precision of prior measured or recommended values.
