Hydrogen atom in phase space. The Kirkwood-Rihaczek representation [PDF]

, 2002
We present a phase-space representation of the hydrogen atom using the Kirkwood-Rikaczek distribution function. This distribution allows us to obtain analytical results, which is quite unique because an exact analytical form of the Wigner functions ...

On-Surface Synthesis with Atomic Hydrogen [PDF]

ACS Nano, 2020
Surface-assisted synthesis has become a powerful approach for generation of molecular nanostructures, which could not be obtained via traditional solution chemistry. Nowadays there is an intensive search for reactions that could proceed on flat surfaces in order to boost the versatility and applicability of synthesized nano-objects.

Hydrogen atom in phase space: The Wigner representation [PDF]

, 2005
We have found an effective method of calculating the Wigner function, being a quantum analogue of joint probability distribution of position and momentum, for bound states of nonrelativistic hydrogen atom. The formal similarity between the eigenfunctions

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

Proceedings 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.
