Predicting L=1/2 output

[blondegeek]

I've had several requests over time for predicting magnetic moments. It seems to me that the simplest way to handle this would be to use spin spherical harmonics for kernels and expressing intermediate tensors. This is essentially adding a second representation index that has Rs = [(1, 1/2)]. We would still need Clebsch-Gordan coefficients to handle the second representation index (which is contracted separately from the first representation index), but we would only need it for 1/2 $\otimes$ 1/2 -> 0 $\oplus$ 1 as we can always readjust our intermediate tensors to have a second representation index solely made of L=0 and L=1/2.
