In reply to Eric Walker's message of Mon, 7 Sep 2015 09:58:50 -0500: Hi, Reactions 2 & 3 are wrong. In 2 you are missing a neutron on the right hand side. In 3 you are missing 2 neutrons on the right hand side. (multiples of about 900 MeV are usually a dead giveaway that you are missing nucleons which mass about that much).
