TLDR
In this article, the neon and xenon isotope anomalies observed in meteorites can be interpreted in terms of a mass fractionation, which is common for both elements and is not necessary to assume the existence of large excesses of fission-type xenon in carbonaceous and gas-rich chondrites.Abstract:

Nitrogen abundances and isotopic compositions in stony meteorites
Chun-Chan Kung,Robert N. Clayton +1 more
TL;DR: In this paper, four major isotopic groups are recognized: (1) C1 and C2 carbonaceous chondrites, (2) enstatite chondrite, (3) C3 chondites, and (4) ordinary chondritic.

Xenon in Carbonaceous Chondrites
TL;DR: Carbonaceous chondrites contain two isotopically distinct components of trapped xenon which cannot be explained by the occurrence of nuclear or fractionation processes within these meteorites.

Rare gases in the chondrite renazzo
J. H. Reynolds,Grenville Turner +1 more
TL;DR: In this article, a detailed analysis of the rare gas content of the chondrite Renazzo is presented, where fraction of different isotopic composition are separated by heating the sample to successively higher temperatures.

A Redetermination of the Relative Abundances of the Isotopes of Neon, Krypton, Rubidium, Xenon, and Mercury
TL;DR: In this paper, a careful redetermination of isotopic abundance ratios in neon, krypton, rubidium, xenon, and mercury has been made, and a mass spectrometer employed was calibrated for mass discriminative effects with a synthetic argon isotope mixture made from essentially pure samples of ${\mathrm{A}}^{36}$ and ${ √ A}}^{40}$.

Notizen: A Redetermination of the Isotopic Composition of Atmospheric Neon
P. Eberhardt,O. Eugster,K. Marti +2 more
TL;DR: A redetermination of the isotopic composition of atmospheric neon gave abundance ratios 20Ne/22Ne = 9.23 ± 0.002 for 20Ne, 21Ne and 22Ne, respectively.
