Résumé :

Some U(n) Racah coefficients appearing in various applications of vector coherent state and K-matrix theories are calculated: For such a purpose, use is made of their definition in terms of U(n):U(n - 1) reduced Wigner coefficients and U(n - 1) Racah coefficients. By starting from known U(2) Racah coefficients, the recursion relations obtained are solved by induction over n. © 1990 American Institute of Physics.
