The original heavy nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma rays and free neutrons; collectively known as fission products.

This fission then releases energy and also neutrons, which then create more tritium from the remaining lithium-6, and so on, in a continuous cycle.

Replies: Most of the early transuranics, such as plutonium, are made in fission reactors in which the nuclear fissions release neutrons.

Beryllium also releases neutrons under bombardment by gamma rays.

Most nuclear reactors use a chain reaction to induce a controlled rate of nuclear fission in fissile material, releasing both energy and free neutrons.

Nuclear fission is the process of splitting a nucleus into roughly equal parts, and releasing energy and neutrons in the process.

Nuclear weapons require "fissile" nuclei, which split apart, releasing energy and neutrons when contacted with slow-moving neutrons.

The heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and free neutrons.

These neutrons collide with other uranium atoms and to release additional heat and neutrons in a chain reaction.

Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction.
