Notizen: A redetermination of the isotopic composition of atmospheric neon

Abstract

A redetermination of the isotopic composition of atmospheric neon gave abundance ratios 20 Ne/ 22 Ne = 9.80 ±0.08 and 20 Ne/ 21 Ne = 338.0 ±2.5, corresponding to percentage abundances of 90.50 ± 0.07, 0.268 ±0.002 and 9.23 ±0.07 for 20 Ne, 21 Ne and 22 Ne, respectively. These abundances correspond to an atomic weight of 20.179±0.002 for atmospheric neon. © 1965, Walter de Gruyter. All rights reserved.
