A note on matrix elements of finiteU(n) transformations

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Matrix elements of finite transformations of the group U(n) in an arbitrary unitary irreducible representation of U(n) are discussed and a technique for their determination is presented. As a by-product a recursion relation for a special Racah coefficient of U(n) is obtained.
