"When a slow moving neutron enters the nucleus of
uranium-235, it creates a turmoil in the structure of the nucleus. All the
nucleons get disturbed and nuclear structure starts oscillating. The
oscillations first give rise to a waist like structure. This proceeds to narrow
and there develops a neck like structure. Further rapid movements make the neck
even more elongated, which ultimately breaks. The break up leads to two smaller
nuclei around the masses of barium and krypton. They can be cesium and rubidium
also. When a 23592U undergoes
fission, it generates three neutrons. These neutrons in turn go and initiate
fission in other 23592U nuclei. Once one single slow
neutron starts a fission in 23592U, the reactions in other
23592U are sustained by the first fission phenomenon
itself. This is called a chain reaction. Very large amounts of energy is
released with each fission, therefore it can be imagined how much energy is
released in a continuous chain reaction."
