Why does the fusion reaction of light nuclei occur only at very high temperatures?
November 14, 2020 | Education
| For the fusion of nuclei, it is necessary that positive nuclei overcome the forces of Coulomb repulsion and approach each other at a distance of the order of the size of the nuclei. for this they must have high kinetic energy, which is possible at a very high temperature – about 10 ^ 8 K
Temperature is a measure of the kinetic energy of particle motion. Such temperatures can be obtained, for example, by pre-using a nuclear reactor or using laser beams.
