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. | ||
pep reaction | once in 400 p-p reactions | proton-proton chain | A reaction occurring in the proton-proton chain which occurs only once in 400 p-p reactions but produces far more energetic neutrinos (1.44 MeV as against 0.42 MeV). |
