Fusion occurs when two nuclei are combined to form a larger element. The problem encountered
when creating a fusion reaction is overcoming the Coulomb Barrier. This barrier is where the protons
in a nucleus repel the protons in the other nucleus. Fusion occurs in stars, where there is so much
mass that the gravity of the star creates enough pressure to push atoms past the Coulomb Barrier.
The most common reaction found in stars is: p+p->d+e++v Where p=proton, d=deuteron, e+=positron, and v=lepton. |
