The reaction rate density between species A and B, having number densities n A,B, is given by: = where k is the reaction rate constant of each single elementary binary reaction composing the nuclear fusion process: = here, σ(v) is the cross-section at relative velocity v, and averaging is performed over all velocities.
Nuclear fusion–fission hybrid (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s, but largely remained unexplored until a revival of interest in 2009, due to the delays in the ...
Diagram showing the Sun's components. The core is where nuclear fusion takes place, creating solar neutrinos. A solar neutrino is a neutrino originating from nuclear fusion in the Sun's core, and is the most common type of neutrino passing through any source observed on Earth at any particular moment.
The first of these, the proton-proton (pp) reaction is the simpler, as well as the more common, of the two. Most people realize our Sun is producing light and heat from the fusion of hydrogen into ...
Scientists have achieved record breaking temperatures within an ‘artificial sun’ reactor, marking a major advance in the development of nuclear fusion energy.. The new world record saw a ball ...
Scientists at a U.S. government lab have announced a breakthrough in efforts to create technology that could one day offer humanity a clean, unlimited source of energy.
The majority of neutrinos which are detected about the Earth are from nuclear reactions inside the Sun. At the surface of the Earth, the flux is about 65 billion (6.5 × 10 10) solar neutrinos, per second per square centimeter. [14] [15] Neutrinos can be used for tomography of the interior of the Earth.

Nuclear reactions due to cosmic rays. By convention, these reaction-products are not termed "nucleogenic" nuclides, but rather cosmogenic nuclides. Cosmic rays continue to produce new elements on Earth by the same cosmogenic processes discussed above that produce primordial beryllium and boron.
