Nuclear Fusion Reaction In a human-scale model of a nuclear fusion reaction, two "deuterons" smash together head-on. Each has a mass of 2.0147kg and is moving at speed vd. The result is a "Helium-3 nucleus" (mass 3.0160kg) and a separate "neutron" (mass 1.0090kg). Amazingly, this reaction produces a positive Wnc of 3.96 × 10 14 J -- by converting mass into kinetic energy as predicted by Einstein's E mc² = The "neutron" moves with a speed of un after the reaction.
