New sum rules for Wigner 3jm symbols: application to expectation values of hydrogenic ions

Jean-Christophe Pain, Franck Gilleron

We present new sum rules for $3 j m$ coefficients, which involve, in addition to the usual weighting factor $(2 j + 1)$ where $j$ is an angular momentum, the quantity $[j (j + 1)]^{k}$ w…

Group theory and the link between expectation values of powers of $r$ and Clebsch-Gordan coefficients

Jean-Christophe Pain

In a recent paper [J.-C. Pain, Opt. Spectrosc. $218$ , 1105-1109 (2020)], we discussed the link between expectation values of powers of $r$ and Clebsch-Gordan coefficients. In…
