This crystal can split light particles

Can this be possible that one photon that is incident on the crystal gets absorbed making particles (2 electrons with same energy but different spins, lets say) to jump to excited states and then these excited electrons come back to their ground states emitting two photons of equal energy but due to change in spin can cause change in direction.. 
Or 1 photon absorbed by 1 electron and this excited electron comes back to ground state in two stages and so when coming down from excited state to intermediate state emits one photon and when from this intermediate state to ground state emitting another photon (but this case will have delay in two photons production). So I guess first case is much better. Also, if this happens like one in million (or whatever) cases then it might be true.
