Fusion. When 2 light nuc particles combine / ‘FUSE’ together – energy is released. Why? Because the product nuclei have less mass than the original particles. How can such fusion be caused? By bombarding particles with charged particles – using an accelerator; or
[thermonuclear reaction a nuclear fusion reaction occurring at a very high temperature: responsible for the energy produced in the sun, nuclear weapons, and fusion reactor]
The term thermonuclear is applied to reactions induce by high thermal energy.
E = [3/2]kT
Even if E is as low as 10 KeV, the temp is –
T = [2/3][(104 eV)(1.6 x 10-19 J/eV)]/[1.38 x 10-23 J/0K]
= 77,000,000 0K.
The fusion of two nuclei with lower masses than iron (which, along with nickel, has the largest binding energy per nucleon) generally releases energy,
