Evolution of the experimental ground-state tunneling period\(\Delta t\)as a function of publication year, including an ambiguity in the first experiment52. DD/HH/DH marks the isotope pattern of the two other hydrogens in the CD/CH bond. See text for further details. ...
The mass defect for an isotope was found to be 0.410 amu/atom. Calculate the binding energy in kJ/mol of atoms. Calculate the total mass of the protons and electrons in 19 9F. Use 1.007825 amu as the mass of 11H (mass of a proton and an electron)...
This paper examines the controls on the stable hydrogen and oxygen isotope compositions of Fe3+-rich, glauconite-nontronite, talc-nontronite and talc-saponite from submarine hydrothermal sites, with a focus on the Red Sea Atlantis II Deep. Values of δ18O became less positive in the order ...

Hydrogen and oxygen isotope ratios (as D:H and 18O:l6O respectively) are expressed in delta notation as 'per mil' or parts per thou- sand (‰) relative to the Vienna Standard Mean Ocean Water (VSMOW)-Standard Light Antarctic Precipitation (SLAP) isotopic scale with accuracy determined to ...
The electrical device may be for example an electrolysis cell, a water vapour pressure meter, an electrochromic cell, a battery, a hydrogen purifier, a hydrogen-isotope enricher, a proton-sensitive electrode (e.g. for a pH meter) or a fuel cell, in which the fuel may be hydrogen. ...
