Barrier transparency and quantum tunnling

Dears
what is "barrier transparency" and what is "quantum tunnling" in fusion?

In fusion, two nuclei have to get extremely close to one another - this means overcoming the large energy barrier (Coulomb Barrier) created by the electrostatic repulsion between the two nucleon's protons. Quantum tunneling is critical for nuclear fusion to occur, because the nuclei involved do not classically have enough energy to overcome the Coulomb barrier and fuse from kinetic energy alone. If they have close to enough energy, they can tunnel through the remaining barrier.

Barrier Transparency, is often approximated by the http://en.wikipedia.org/wiki/Gamow_factor" , which is the probability for two nuclei to overcome the Coulomb barrier and undergo fusion.

Hello,

"Barrier transparency" refers to the phenomenon in which particles or energy can pass through a potential energy barrier, even though classically they do not have enough energy to overcome it. This is observed in nuclear fusion, where two atomic nuclei with positive charges must overcome a repulsive electrostatic barrier to fuse together and release energy. In the quantum world, particles can tunnel through this barrier due to their wave-like nature, allowing fusion to occur even at lower temperatures and energies.

"Quantum tunneling" is the same concept but applied to individual particles, such as electrons. In quantum mechanics, particles can exist in multiple energy states simultaneously, and they can also tunnel through barriers that they do not have enough energy to overcome classically. This is an important phenomenon in many fields, including fusion, where it allows particles to overcome the repulsive barrier and fuse together.

I hope this helps to clarify these concepts for you. Let me know if you have any further questions.
