Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Stern–Gerlach experiment | Statement: [Stern–Gerlach Medal, namedAfterExperiment, Stern–Gerlach experiment]

Target entity: Stern–Gerlach experiment
Context triple: [Stern–Gerlach Medal, namedAfterExperiment, Stern–Gerlach experiment]

• A. Franck–Hertz experiment
  The Franck–Hertz experiment is a landmark early-20th-century physics experiment that provided direct evidence for the quantization of atomic energy levels, supporting the Bohr model of the atom.
• B. Davisson–Germer experiment
  The Davisson–Germer experiment was a landmark 1927 physics experiment that demonstrated the wave nature of electrons through diffraction from a nickel crystal, providing key evidence for quantum mechanics and wave–particle duality.
• C. Ives–Stilwell experiment
  The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
• D. Eötvös experiment
  The Eötvös experiment is a classic physics test of the equivalence principle that measures whether different materials fall with the same acceleration in a gravitational field.
• E. Foucault experiment
  The Foucault experiment is a 19th-century optical test devised by Léon Foucault to measure the speed of light with high precision using a rotating mirror apparatus.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Stern–Gerlach experiment
Triple: [Stern–Gerlach Medal, namedAfterExperiment, Stern–Gerlach experiment]

The Stern–Gerlach experiment is a landmark quantum physics experiment that demonstrated the quantization of particle spin by passing silver atoms through a non-uniform magnetic field and observing their discrete spatial separation.
