The energy released (the Q value ) in the fission reaction of nuclei like
uranium is of the order of 200 MeV per fissioning nucleus This is
estimated as follows:
Let us take a nucleus with A = 240 breaking into two fragments each
of A = 120 Then
Ebn for A = 240 nucleus is about 7 6 MeV,
Ebn for the two A = 120 fragment nuclei is about 8
