The Coulomb barrier is the energy barrier due to electrostatic interaction that nuclei need to overcome to get close enough for nuclear fusion. Overcoming this barrier requires sufficient kinetic energy, typically through high temperatures or external forces in a controlled environment such as a fusion reactor or stellar core.

Coulomb Barrier

An energy barrier is a potential energy threshold that must be overcome for a chemical reaction or physical process to occur. It represents the activation energy required to initiate a transformation, influencing the rate and feasibility of reactions.

Energy Barrier

Electrostatic interaction refers to the force between charged particles, governed by Coulomb's law, where opposite charges attract and like charges repel. This fundamental force plays a crucial role in chemical bonding, molecular interactions, and the behavior of materials at the atomic level.

Nuclei

Nuclear fusion is the process by which two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy due to the conversion of mass into energy as described by Einstein's equation, E=mc². It is the same reaction that powers the sun and stars, and holds the potential for providing a nearly limitless, clean energy source on Earth if technological and material challenges can be overcome.

Nuclear Fusion

Kinetic energy is the energy possessed by an object due to its motion, and it is directly proportional to the mass of the object and the square of its velocity. This form of energy is a fundamental concept in physics, playing a crucial role in understanding the dynamics of systems and the conservation of energy principle.

High Temperatures

External forces are influences originating outside a system that can affect its behavior, performance, or structure. They play a crucial role in fields like physics, economics, and business, determining how systems interact with their environments and adapt to changes.

External Forces

A controlled environment refers to a setting where variables are regulated to maintain specific conditions, often to optimize growth or performance. This is crucial in fields like agriculture, research, and manufacturing, where precise control over environmental factors can significantly impact outcomes.

Controlled Environment

A fusion reactor is a device designed to harness the energy produced by nuclear fusion, the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy. It holds the promise of providing a nearly limitless, clean, and safe energy source, but achieving the conditions necessary for sustained fusion reactions remains a significant scientific and engineering challenge.
