The first step of this process usually takes 109 years as the Coulomb potential is difficult to overcome via tunneling and the weak force.
The first step of this process can occur via electron capture and creates discrete spectral lines of neutrinos at 1.44MeV as compared to the usual spectral lines of 0.42MeV for this process. Part of the solution to the neutrino problem comes from the fact that this process can generate neutrinos with 14.06MeV. This process may create beryllium, which then becomes lithium via electron capture. The first step of this process usually takes 109 years as the Coulomb potential is difficult to overcome via tunneling and the weak force. The second step of this process sees the formation of helium-3 from deuterium, which is made from the first step. For 10 points, name this process that creates helium-4 from four hydrogen atoms and that generates most of the energy in the Sun.
