---|---|---|---|---|
proton-proton chain | pycnonuclear reaction | An important nuclear fusion reaction that occurs in stars. It begins with the fusion of two hydrogen nuclei, each of which consists of a single proton. | ||
PP II | 1H(p, β+v)2D(p, γ)3He(4He, γ)7Be(β+v)7Li(p,α)4He | proton-proton chain | A thermonuclear reaction in which hydrogen nuclei are transformed into helium nuclei. Although the neutrinos from this reaction are detectable, they have not been observed. |
