How this entity was disambiguated
This entity first appeared as the object of triple T13469173 — 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: Mössbauer effect Context triple: [Rudolf Mössbauer, knownFor, Mössbauer effect]
-
A.
Mössbauer Spectrometer
The Mössbauer Spectrometer is a highly sensitive instrument that uses gamma-ray resonance absorption to determine the mineralogical and chemical composition of iron-bearing rocks and soils.
-
B.
Shubnikov–de Haas effect
The Shubnikov–de Haas effect is a quantum oscillatory phenomenon in the electrical resistance of conductors and semiconductors subjected to strong magnetic fields at low temperatures, used to probe their electronic structure and Fermi surface.
-
C.
Szilard–Chalmers effect
The Szilard–Chalmers effect is a nuclear chemistry phenomenon in which atoms that undergo neutron capture and become radioactive are chemically separated from their original, non-activated atoms due to recoil-induced disruption of their chemical bonds.
-
D.
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.
-
E.
Slichter–Hebel coherence peak
The Slichter–Hebel coherence peak is a characteristic enhancement in nuclear spin-lattice relaxation just below the superconducting transition temperature, providing key experimental evidence for conventional BCS superconductivity.
- F. None of above. chosen
