Does anyone know what the formula is for the following:(adsbygoogle = window.adsbygoogle || []).push({});

<j m | S^2_{+} |j m > = ?

Reference to equations in Sakurai would be helpful in deriving the relation. I would suspect 3.5.37 but what about the delta_j j' ?

Does anyone know what I'm talking about?
