How I understand it, the first time the atom was "split", it was done by creating beryllium-8 which has such a small half-life that it immediately decays into two helium-4 atoms (alpha particles). Since each helium-4 atom is a half of a full beryllium atom, the beryllium-8 atom has basically been split. But when people talk about "splitting" an atom, their usually talking about fusion right, not just some atom that just so happens to be twice as large as its decay products. Also, this beryllium-8 atom is the atom that IDers talk about in the triple alpha process. Here is a quote from wikipedia: "The triple alpha proceess is highly dependant on carbon-12 having a resonance with the same energy as helium-4 and beryllium-8 and before 1952 no such energy level was known. It was astrophysicist Fred Hoyle who used the fact that carbon-12 is so abundant in the universe and that our existence depends upon it - what is now called the Anthropic Principle, as evidence for the existence of the carbon-12 resonance. Fred suggested the idea to nuclear physicist Willy Fowler, who conceded that it was possible that this energy level had been missed in previous work on carbon-12. After a brief undertaking by his research group, they discovered a resonance near to 7.65 Mev and the rest is theory." I think the first time I read about it was on a creationist or ID website. How they explained it, or at least, how I understood it, was that 2 hellium atoms couldn't combine to create anything, but 3 could because carbon-12 happend to have the correct energy level, which meant that the alpha chain of fusion could skip over the broken spot in the chain and thus life could form. But if that's no true, then what makes it so much more amazing than the other fusion reactions that take place in stars. Does no other element need a specific energy level for fusion to occur with helium?
