Photoemission Studies of Energy Levels in the Palladium-Hydrogen System
Abstract
Photoemission studies of the Pd/H system show a band of hydrogen-induced energy states centered at 1 eV below the bottom of Pd-derived d bands of width 4.4 eV. These results show that the widely accepted simple "proton model" of Pd/H is misleading. Our augmented-plane-wave calculations of PdH, ${\mathrm{Pd}}_{4}$${\mathrm{H}}_{3}$, and ${\mathrm{Pd}}_{4}$H exhibit these lowlying states and also explain why the added number of electrons (0.6) in $\ensuremath{\beta}$-phase PdH exceeds the number of $d$-band holes (0.36) in Pd.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
