Question: We calculated the energy threshold for the reaction p + p p + p + p + p on free protons as targets in

We calculated the energy threshold for the reaction p + p → p + p + p + p on free protons as targets in Problem 1.9. Repeat the calculation for protons that are bound in a nucleus and have a Fermi momentum of p_f = 150 MeV. For the incident proton use the approximation p_p ⋍ Ep.
