Question:
A photon of energy E is incident on a deuteron at rest. In the center-of-mass reference frame, both the photon and the deuteron have momentum p. Prove that the approximation p ≈ E/c is good by showing that the deuteron with this momentum has energy much less than E. If the binding energy of the deuteron is 2.22 MeV, what is the threshold energy in the lab for photodisintegration?
