I have a textbook that says that photons have a spin of absolute value $\hbar$ and at some other point, they say that it has angular momentum of absolute value $\hbar$. Now, since they are different things, I was asking myself: Is it maybe right to say, that it is a spin that is transformed into angular momentum when the photon is absorbed by matter?

I would be glad if anybody here could write down a few clarifying sentences about this topic.

Spin and angular are synonyms in this case: en.wikipedia.org/wiki/Spin_(physics) –  jinawee Oct 26 '13 at 13:58
