Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit of positive electric charge, called a proton. In common usage, the term hydrogen ion is used to
Hydrogen ions affect the solubility of most other ions in soil solution; thus, pH is often considered the master variable that controls soil nutrient availability. In time, most forest soils become more acid because plant roots selectively absorb more nutrient cations than anions, releasing H+ in...
We consider the controversial conclusions of the charge at the migrating hydrogen in the transition state of hydride-transfer reactions from CH-groups to hydride acceptors. Quantum chemical calculations were performed on elementary organic reactions involving carbenium ions, which can be considered as hyd...
Towards a specific reaction parameter density functional for reactive scattering of H2 from Pd(111) In this work, the SRP-DFT methodology is applied to the dissociation of hydrogen on a Pd(111) surface, in order to test whether the SRP-DFT ... JM Boereboom,M Wijzenbroek,MF Somers,... ...
The target was a 20-cm-long Z pinch discharge which provided fully ionized hydrogen plasma with free electron densities up to 1.5×1019 cm-3. The measured charge-state distributions are in excellent agreement with theoretical calculations. For Xe ions an increase of the ion charge state in ...
A transient plasma column is produced by discharging a 0.1 μF-capacitor at 20 kV along a beam of hydrogen clusters. The time dependance of the ion density is obtained from Stark broadening measurements of Hβ (4861 ). A maximum density of 6.6 × 1016 ions/cm3 is achieved, the initial ...
Charge transfer of O^{3+} ions in collisions with atomic hydrogen Cross sections are calculated for the charge transfer of ${mathrm{O}}^{3+}$ ions in collisions with hydrogen atoms. The cross sections are in satisfactory agreement with ion-trap measurements at energies near 2.5 eV and with...
