A high energy photon (gamma ray) can under certain conditions eject a neutron from a nucleus. Thermal Reactors. Since the proton is the lightest particle among all baryons, the hypothetical products of its decay would have to be non-baryons. A nuclear power plant uses the heat that a nuclear reactor produces to turn water into steam, which then drives turbine generators that generate electricity. A further reactor type, the so-called fast reactor, has been developed to full-scale demonstration stage. January 1993.

Thus, a nuclear reaction must cause a transformation of at least one nuclide to another. Standard nuclear notation shows (see picture) the chemical symbol, the mass number and the atomic number of the isotope. Notwithstanding, any reaction not expressly forbidden by the conservation laws will generally occur, if perhaps at a slow rate. On the other hand, the following reaction (proton-antiproton pair production) does conserve B and does occur if the incoming proton has sufficient energy (the threshold energy = 5.6 GeV): As indicated, B = +2 on both sides of this equation. $.'
