The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. It dominates in stars with masses less than or equal to that of the Sun, whereas the CNO cycle, the other known reaction, is suggested by theoretical models to dominate in stars with masses greater than about 1.3 times that of t… WebThe PPIII chain will become the dominant of the three main proton-proton processes in a star with a core temperature above 23 million Kelvins. The CNO Cycle. For the very first …

Webchain, but one in 10,000 7Be nuclei captures a proton to make 8B (Fig. 2, Table 1). Boron-8 decays to 8Be, which splits to make two 4He nuclei, a positron, and an electron neutrino, completing the PPIII chain. It is these 8B neutrinos that produce most of the solar neutrino signal I detected, but there Webchain, but one in 10,000 7Be nuclei captures a proton to make 8B (Fig. 2, Table 1).

WebIn part of the ppIII chain a proton collides with a Be nucleus to form B. Calculate the Gamow energy for this reaction and the most likely energy at which this reaction would occur in a star with a core temperature of 107 K. Give both of your answers in eV.
