http://www.msrblog.com/science/physics/nucleosynthesis.html WebThis 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. hemingway drinking quotes
