Coherent States for the Hydrogen Atom [PDF]

, 1995
The long-standing problem of finding coherent states for the (bound state portion of the) hydrogen atom is positively resolved. The states in question: (i) are normalized and are parameterized continuously, (ii) admit a resolution of unity with a ...

First principle study of hydrogen behavior in hexagonal tungsten carbide

, 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.

Bis{2-[bis(2-hydroxyethyl)amino]acetato-κ3O,N,O′}zinc(II)

Acta Crystallographica Section E, 2010
In the crystal structure of the zinc(II) complex of bicine, [Zn(C6H12NO4)2], the deprotonated amino acid O,N,O′-chelates to the metal atom through a carboxylate O atom, a hydroxy O atom and the N atom, the three atoms occupying fac positions of

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

, 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.

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

, 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.

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

, 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.

2s Hyperfine Structure in Hydrogen Atom and Helium-3 Ion [PDF]

, 2001
The usefulness of study of hyperfine splitting in the hydrogen atom is limited on a level of 10 ppm by our knowledge of the proton structure. One way to go beyond 10 ppm is to study a specific difference of the hyperfine structure intervals 8 Delta nu_2 -
