Excited state muon transfer in hydrogen/deuterium mixtures.
We report the first direct observation of excited state muon transfer in hydrogen/deuterium mixtures by direct measurement of q1s, the probability that a μp atom, which is initially formed in an excited state, reaches the 1s ground state. The dependence of q1s on deuterium concentration cd was measured for two different densities at cryogenic temperatures using charge coupled devices (CCDs) to ...
متن کاملMechanisms for thermal conduction in hydrogen hydrate.
Extensive equilibrium molecular dynamics simulations have been performed to investigate thermal conduction mechanisms via the Green-Kubo approach for (type II) hydrogen hydrate, at 0.05 kbar and between 30 and 250 K, for both lightly filled H(2) hydrates (1s4l) and for more densely filled H(2) systems (2s4l), in which four H(2) molecules are present in the large cavities, with respective single...
متن کاملSolar System Deuterium/Hydrogen Ratio
The D/H variations in chondritic meteorites are reviewed and compared with astronomical observations in the interstellar medium. The observed D enrichment in organic molecules — and to a lesser extent in water — is a general rule in the universe. The D is preferentially transferred from the universal reservoir (H2) by low-temperature reactions (10–100 K) from neutral molecules (H2 or H) to hot ...
متن کاملRapid Hydrogen-Deuterium Exchange in Liquid Droplets.
The rate of hydrogen-deuterium exchange (HDX) in aqueous droplets of phenethylamine has been determined with submillisecond temporal resolution by mass spectrometry using nanoelectrospray ionization with a theta-capillary. The average speed of the microdroplets is measured using microparticle image velocimetry. The droplet travel time is varied from 20 to 320 μs by changing the distance between...
متن کاملUrea and deuterium mixtures at high pressures.
Urea, like many network forming compounds, has long been known to form inclusion (guest-host) compounds. Unlike other network formers like water, urea is not known to form such inclusion compounds with simple molecules like hydrogen. Such compounds if they existed would be of interest both for the fundamental insight they provide into molecular bonding and as potential gas storage systems. Urea...
