Nuclear Fusion Reaction
Nuclear Fusion Reaction
When lighter atomic nuclei are fused together to form a larger nucleus by the action of a very high temperature, this process is called Nuclear Fusion Reaction.In the fusion process, the mass of resultant large nuclei is smaller than the sum of the masses of the fused nuclei. Hence the mass difference Δm is converted into energy according to the Einstein equation-
E= Δm x C2
Thus lighter elements like Deuterium nuclei are fused togther by the heat, generated by nuclear fission reaction (100000°C), much larger energy is liberated and the temperature might rise to about 1000000°C. This is the principle of hydrogen bomb.
According to Bethe, nuclear fusion reaction is occuring in the Sun and tremendous quantity of heat and light are being continuously emitted by it. Probably the following fusion reactions occur in the Sun-
It has not been yet possible to control this reaction to utilize the tremendous amount of energy of nuclear fusion reaction for useful purposes.
