Key Concepts

Nuclear Fusion

Nuclear fusion is the process by which two light nuclei combine to form a heavier nucleus, releasing energy due to the mass difference between the reactants and the products. This process requires the nuclei to come sufficiently close to each other for the strong nuclear force to overcome the electrostatic repulsion between their positively charged protons.

Coulomb Barrier

The Coulomb barrier refers to the energy barrier resulting from the electrostatic repulsion between two positively charged nuclei. Overcoming this barrier is crucial for fusion because the nuclei must have enough kinetic energy to get close enough for the attractive strong nuclear force to take over and bind them together.

Threshold Energy

Threshold energy is the minimum total kinetic energy required for the reactant nuclei to overcome all repulsive forces such as the Coulomb barrier. In a fusion reaction, this energy ensures that the nuclei approach each other sufficiently to allow the nuclear forces to initiate the fusion process.

Kinetic Energy

Kinetic energy in the context of nuclear reactions represents the energy of motion of the nuclei. For a fusion reaction to occur, the kinetic energy must be high enough not only to sustain the collision but also to provide the necessary energy to surpass the Coulomb barrier, making fusion possible.
