Say a uranium238 nucleus with angular momentum I_{I} decays to thorium234 plus an alpha particle. Will the sum of the angular momenta of the thorium234 nucleus and the alpha particle equal I_{I}? What if a photon was emitted during this process, would I_{thorium}+I_{α}+hbar=I_{I}?
thanks

The relative motion of the nuclei can carry angular momentum, so the result can be different.

To clarify mfb's point, orbital angular momentum must be included when applying angular momentum conservation. But yes, angular momentum is definitely always conserved.
