This seems like something of a misnomer, since "atomic" is generally applied to reactions involving the valence electrons. The energy from a fission reaction, while evidenced after the fact as the repulsion of high-Z like-electric fields, still comes from the nuclear binding energy. Fission is a weak nuclear process; the nuclei involved are at the high end of the binding energy curve, where the first derivative is small compared to lower-end processes (e.g., fusion). When you figure in energy as a function of mass, then the disparity between fission and fusion becomes all the more discernable. The term "atomic" bomb was misapplied. Some may recall an old H.G. Wells story (c. turn of the century) in which there was a "nuclear bomb" -- in actuality, this device derived it's energy from purely atomic forces (as conventional high explosives). So, misapplication of scientific terms is nothing new, even in the bomb business. -shane
