Webb9 jan. 2024 · The reaction is 2 H + 1 H → 3 He + γ. E2 The final step in the reaction chain, which is called the proton-proton cycle, takes place when a second 3 He nucleus, created in the same way as the first, collides and fuses with another 3 He, forming 4 He and two protons. In symbols, 3 He + 3 He → 4 He + 2 1 H. E3 WebbNuclear fusion reaction powers a star for most of its life. When a protostar born from nebulae or molecular settles down, it becomes a main-sequence star, and fusion reaction happens in its core. The primary nuclear fusion happens in the star core is the conversion of proton to helium.
