... We observe that (4.15) is actually a system of uncoupled equations, one for each fixed value of the orbital angular momentum quantum number l . With reference to the wave equation in one dimension, the extra term involving l(l + 1) in (4.15) represents the contribution to the potential field due to ...

The Addition Theorem for Spherical Harmonics and Monopole
... The key point is to observe that the angular momentum operators in both cases satisfy the same SU(2) algebra. The only difference is that, for ordinary angular momentum operators L, they satisfy ^r:L = 0, where ^r is the radial unit vector. For the monopole angular momentum operators J, we have the ...
