Abstract
“Absolute” values for the isotopic abundance ratios of atmospheric neon have been determined by mass spectrometry. Calibration standards were prepared by mixing of nearly pure separated nuclides of neon. The percentage abundance of the three nuclides of neon are:
20Ne = 90.514 ± 0.031, 21Ne = 0.266 ± 0.005, 22Ne =9.220 ± 0.029.
The calculated atomic weight of neon on the unified physical and chemical atomic weight scale (12C=12) is 20.1794 ± 0.0030.
