Lamb shift
E1555160
UNEXPLORED
The Lamb shift is a small difference in energy levels of the hydrogen atom, revealed by precision spectroscopy and explained by quantum electrodynamics as arising from interactions between the electron and vacuum fluctuations.

How this entity was disambiguated
This entity first appeared as the object of triple T22793306 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Lamb shift Context triple: [Willis Eugene Lamb, knownFor, Lamb shift]
-
A.
Rydberg constant
The Rydberg constant is a fundamental physical constant that characterizes the limiting value of the highest wavenumber (or lowest wavelength) of any photon that can be emitted from the hydrogen atom, playing a key role in atomic spectroscopy and quantum theory.
-
B.
Zitterbewegung
Zitterbewegung is a rapid, trembling motion predicted for relativistic quantum particles, arising from interference between positive and negative energy states in the Dirac equation.
-
C.
Stark effect
The Stark effect is the splitting and shifting of atomic or molecular spectral lines caused by an external electric field.
-
D.
Sommerfeld fine-structure formula
The Sommerfeld fine-structure formula is a relativistic extension of the Bohr model that accurately predicts the fine-structure energy levels of the hydrogen atom.
-
E.
Segré–Silberberg effect
The Segré–Silberberg effect is a fluid dynamics phenomenon in which particles suspended in laminar flow through a circular tube migrate to stable equilibrium positions at a characteristic radial distance from the tube wall.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
