The Collective Term For the Nuclear Reactions Evolution |
Nuclearfusion rates are extremely sensitive to temperature. In order to understand whythis is so, we need to examine how a fusion process operates: since thepositively charged nuclei which need to fuse have to face a strong coulombbarrier (see fig. 1), the fusion process operates mainly by tunnelling. In thecentre of mass frame, if the kinetic energy of the approaching particles is E,then the tunnelling probability.
