A hopefully, quick issue I just wanted to be clear on before my exam.(adsbygoogle = window.adsbygoogle || []).push({});

One question gave me two quantum numbers for total angular momentum.

j1 = 1 and j2 = 2. The question asks to list the Eigenvalues for toatl angular momentum and its z component.

I think I can do the later part okay by working out the possible combinations of the various m quantum number.

However I'm a little unsure about the first part? Should I be calculating the Eigenvalues for the square of each angular momentum component j1^2 and j2^2, square rooting or adding (or adding an square rooting). Or should I add the numbers together then calculate the Eigenvalue?

Or none of the above

I hope that all made sense
