Abee did not reside on an asteroidal regolith surface for a significant period of time due to the lack of pre-irradiation. This model suggests that the E-chondrite groups formed by metamorphic heating and metal to silicate fractionation on a single parent body. 展开 ...
The rotational dependence of pressure-induced shift and broadening of H2S absorption lines in the ν2 band due to collisions between H2S molecules and atoms of noble gases (He, Ne, Ar, Kr, and Xe) were studied in the spectral region between 1050 and 1325 cm−1. The measurements ...
Spectroscopic studies of noble-gas monohalides Vacuum-UV emission spectra were obtained in a discharge flow system for reactions of bromine-, chlorine- and iodine containing reagents with metastable argon atoms (Ar(3P2~0). Halogen atomic lines were observed for many of these spectra... A Kvaran...

Two distinct processes have been identified: (1) accumulation of atmosphere-derived (ANG) and radiogenic noble gases both initially dissolved in groundwaters, resulting in a positive correlation between absolute amount of ANG and the extent of heavy noble gas fractionation and (2) subsequent ...
Noble gases in natural gas, from Xiaoquan, Xinchang, Hexingchang and Fenggu gas reservoirs in the middle part of the western Sichuan Depression, China, were analysed. Results show that the volume content of crustal noble gases accounts for 97.9% to 99.7% of the total noble gas content, indic...
