Condon-Shortley Phase

Splet1) In principle, one may also introduce a (possibly complex) phase factor in the definition of C ± (j , m) {\displaystyle C_{\pm }(j,m)} . The choice made in this article is in agreement with the Condon–Shortley phase convention . The angular momentum states are orthogonal (because their eigenvalues with respect to a Hermitian operator are distinct) and are … SpletSometimes (e.g., Arfken 1985), the Condon-Shortley phase is prepended to the definition of the spherical harmonics.
