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: LS-coupling Landé formula | Statement: [Landé g-factor, hasApproximation, LS-coupling Landé formula]

Target entity: LS-coupling Landé formula
Context triple: [Landé g-factor, hasApproximation, LS-coupling Landé formula]

• A. Russell–Saunders coupling chosen
  Russell–Saunders coupling is an atomic physics scheme that describes how individual electron orbital and spin angular momenta combine to determine the total angular momentum of an atom, especially in light atoms.
• B. Landé g-factor
  The Landé g-factor is a dimensionless quantity in atomic physics that characterizes the splitting of atomic energy levels in a magnetic field by relating the total angular momentum of an electron or atom to its magnetic moment.
• C. 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.
• D. Wigner–Eckart theorem
  The Wigner–Eckart theorem is a fundamental result in quantum mechanics that factorizes matrix elements of tensor operators into a reduced matrix element and a purely geometric part given by Clebsch–Gordan coefficients, greatly simplifying angular momentum calculations.
• E. Clebsch–Gordan coefficients
  Clebsch–Gordan coefficients are numerical factors in quantum mechanics and representation theory that describe how to combine two angular momenta (or group representations) into a single resultant one.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
