Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In the framework of many-electron theory, the configurational potential relief of hydrogen atom in hexagonal close-packed metals is calculated. Using the data on the quantum states and the interaction mechanisms of impurity atom, two types of hydrogen transport are studied: high-temperature hopping and bandlike movement (tunneling transitions) at very low temperatures. Anharmonicity of hydrogen atom vibration is shown to have an effect on the relaxation processes owing to the interference with phonon scattering.
