in that not all the H atoms can be originally bonded to the same atomic center. Another interesting point is that they make a new bond with the oxygen, versus with each other, undergoing different transition state(s) to reach the final states. H3O+ions have already been observed in ...

The mass spectra was recorded between 1–200 atomic mass units (amu) continuously, with each scan taking 13s from 1 to 200 amu. The atomic mass unit of 2 (m/z = 2) was ana- lyzed for hydrogen. High-Pressure Volumetric Adsorption Analysis. Adsorption measurements were carried...
The cross sections are compared with measured total cross sections for electron capture by N4+ ions in collisions with hydrogen. Agreement is excellent in the collision-energy range from 4.1 to 182 eV/amu. 展开 关键词: N4++H→N3+(2s3l)+H+ charge-transfer sections cross sections N4+ DOI...
