Some properties of Wigner $3 j$ coefficients: non-trivial zeros and connections to hypergeometric functions

Jean-Christophe Pain

The contribution of Jacques Raynal to angular-momentum theory is highly valuable. In the present article, I intend to recall the main aspects of his work related to Wigner $3 j$ sym…

Expression of relativistic expectation values of powers of $r$ in terms of Clebsch-Gordan coefficients

Jean-Christophe Pain

It is shown that, in the relativistic hydrogenic approximation, expectation values of the type $⟨ n ℓ j ∣ r^{k} ∣ n ℓ j ⟩$ can be expressed in terms of Clebsch-Gordan coef…
