why does fission of heavy nuclei tend to produce free neutrons?
In the heavy nuclei, the Coulomb repulsion of the protons become important and thus the heavy nuclei tend to have more neutrons than protons

How much Kinetic energy released and what is the daughter nucleus in the decay of nitrogen-13?
All target nuclei used in MRI have an odd number of protons or neutrons or both. What does this suggest about nuclear spins? (Note: Both the proton and the neutron have gyromagnetic ratios.)
The semi empirical binding energy formula predicts the binding energies of neon-20, iron- 56, and uranium-238 within about 1\%. Make a table whose rows are the three isotopes, whose first four columns are numerical values of the four tennis in the formula, whose next four columns are each of these terms divided byA, and whose final column is the sum of the preceding four. Discuss in some detail what the table reveals.
Using the semiempirical binding energy formula estimate the mass of a europium- atom.
The total kinetic energy carried by the products of the spontaneous fission of plutonium – 240 is typically about 180 MeV. Use this to argue there that reduction in Coulomb repulsion is the major impulse behind the process. Assume for simplicity that the two fragment nuclei are of equal Z.
