Atomic hydrogen - I—The calorimetry of hydrogen atoms [PDF]

open access: yesProceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1937
Since the discovery of Wood (1920, 1921, 1922 a , b ) that hydrogen can be dissociated to a considerable extent into free atoms in the glow discharge, many workers have used this method of production of atomic hydrogen for the study of its chemistry.

Elucidation of the Fourth-Order Generalized Schrodinger Problem for Hydrogen Atom using Frobenius Series Application

open access: yesJournal of Applied Sciences and Environmental Management, 2023
The hydrogen atom is a fundamental system in quantum mechanics that has been extensively studied due to its simplicity and relevance to atomic physics.

2-{1-[2-((2-Ammonioethyl){2-[1-(5-chloro-2-hydroxyphenyl)ethylideneamino]ethyl}amino)ethyliminio]ethyl}-4-chlorophenolate trifluoroacetate

open access: yesActa Crystallographica Section E, 2009
In the title ion-pair, C22H29Cl2N4O2+·C2F3O2−, ammonium–carboxylate N—H...O hydrogen bonds link two cations and two anions about a centre of inversion to generate a hydrogen-bonded tetramer.

Intra- and intermolecular proton transfer in 2,6-diaminopyridinium 4-hydroxypyridin-1-ium-2,6-dicarboxylate [PDF]

open access: yes, 2012
Chelidamic acid (4-hydroxypyridine-2,6-dicarboxylic acid) and 2,6-diaminopyridine react to form the title salt, C5H8N3+·C7H4NO5-; there are two formula units in the asymmetric unit.

First principle study of hydrogen behavior in hexagonal tungsten carbide

open access: yes, 2010
Understanding the behavior of hydrogen in hexagonal tungsten carbide (WC) is of particular interest for fusion reactor design due to the presence of WC in the divertor of fusion reactors.

Ground-state structure of the hydrogen double vacancy on Pd(111)

open access: yes, 2007
We determine the ground-state structure of a double vacancy in a hydrogen monolayer on the Pd(111) surface. We represent the double vacancy as a triple vacancy containing one additional hydrogen atom.

Dispersion of Klauder's temporally stable coherent states for the hydrogen atom

open access: yes, 1998
We study the dispersion of the "temporally stable" coherent states for the hydrogen atom introduced by Klauder. These are states which under temporal evolution by the hydrogen atom Hamiltonian retain their coherence properties.
