Nuclear reaction

Page Editor: Deb Sankar Bhattacharya

In nuclear fusion, two light nuclei combine or fuse together and another nucleus of higher atomic number is produced.

One such process can release lots of energy, β particle and Neutrino (ν), a very low mass, charge less, fast moving particle.

For fusion the parent nuclei should possess very high kinetic energy which is evidently provided by very high temperature. So, for fusion, very high temperature is required and in a star, gravitational collapse generates such high temperature ambient. A very common example of nuclear fusion is the fusion of two protons which occurs in chain wise within a star and is known as p-p chain reaction.
