There are a number of fusion processes but they all result in the creation of some new particles. The most common process in our sun's core is the proton-proton process. The process is something like this: two protons collide and fuse, one deteriorates into a neutron releasing a positron and a very high energy neutrino. The resulting nucleus is deuterium. Another proton fuses with this nucleus forming the light helium isotope. When two of these helium isotopes collides and fuses, a helium nuclei results with two protons expelled at high energy to continue the process. If you add up the masses of the original protons and compare with the resulting particles, the missing mass is the binding energy that was released according to Einstein's famous equation. This process starts in stars where the core temperature is about 700,000 K. Jerry P.S. a good description of this can be found in a new book, "Journey from the Center of the Sun" which I recently reviewed on Amazon.com -- --------------------------------------------------------------------------------- -- Jerry Petrey -- Senior Principal Systems Engineer - Navigation (GPS/INS), Guidance, & Control -- Raytheon Missile Systems - Member Team Ada & Team Forth -- NOTE: please remove in email address to reply ---------------------------------------------------------------------------------
