Webbproton-proton chain, also called p-p chain, proton-proton cycle, or proton-proton reaction, chain of thermonuclear reactions that is the chief source of the energy radiated by the Sun and other cool main-sequence stars. Another sequence of thermonuclear reactions, called the CNO cycle, provides much of the energy released by hotter stars. In a proton-proton … WebbThis is a net reaction of a more complicated series of events: (19.6.1) 4 1 1 H He 2 4 + 2 + 1 0 n. A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about 3.6 × 10 11 kJ of energy per mole of He 2 4 produced.

WebbAn important fusion reaction for practical energy generation is that between deuterium and tritium (the D-T fusion reaction). It produces helium (He) and a neutron ( n) and is … WebbNuclear fusion is a type of nuclear reaction where two light nuclei collide together to form a single, heavier nucleus. Fusion results in a release of energy because the mass of the new nucleus is less than the sum of the original masses.
WebbThe quantum mechanical tunnel effect allows the reaction to proceed at an acceptable rate at lower temperatures: For the D + T reaction the ignition temperature is 3 × 10 7 K and for the D + D and D + 3 He reactions it is 3 × 10 8 K. These reactions are the prime candidates for controlled fusion; see Figure 17.5. WebbVerified answer. physics.

The first step in all the branches is the fusion of two protons into a deuteron. As the protons fuse, one of them undergoes beta plus decay, converting into a neutron by emitting a positron and an electron neutrino (though a small amount of deuterium nuclei is produced by the "pep" reaction, see below): p + p → 1D + e + ν e The first step in all the branches is the fusion of two protons into a deuteron.
