Hylleraas coordinates

Target entity: Hylleraas coordinates
Context triple: [Egil A. Hylleraas, knownFor, Hylleraas coordinates]

• A. 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.
• B. Racah polynomials
  Racah polynomials are a family of classical orthogonal polynomials that arise in the representation theory of angular momentum and in the study of exactly solvable models in mathematical physics.
• C. Clebsch
  Clebsch is a German surname most notably associated with mathematician Alfred Clebsch, known for his contributions to algebraic geometry and invariant theory.
• D. Slater determinant
  A Slater determinant is an antisymmetrized many-electron wavefunction constructed from single-particle orbitals that enforces the Pauli exclusion principle in quantum chemistry and atomic physics.
• E. Plücker coordinates
  Plücker coordinates are a system of homogeneous coordinates used in projective geometry to represent lines (and other subspaces) in higher-dimensional spaces.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Hylleraas coordinates
Target entity description: Hylleraas coordinates are a specialized set of variables used in quantum mechanical calculations of two-electron atoms to more accurately account for electron–electron correlation.
