nucleosynthetic reaction nuclear process

e-process nucleosynthetic reaction A hypothetical group of nuclear reactions by which the iron group is assumed to be synthesized. At temperatures > 5 × 10⁹ K and densities > 3 × 10⁶ g cm^-3 there are great numbers of collisions between high-energy photons and nuclei. These collisions break up the nuclei, the fragments of which promptly combine with other particles. Thus, there is in effect an equilibrium between formation and breakup. Since the iron group has the largest binding energies, the particles over the long run will tend to be trapped in these nuclei. The e-process (the e stands for equilibrium) is presumed to occur in a supernova explosion.
