If we tried to make elements higher than Helium in a terrestrial fusion reactor, what elements could we realistically make? If I've understood it correctly the triple alpha process reaction rates would be irrelevant due to the considerably lower pressure * time product. But how would Be and Li work? Could they be synthesized in a manner similar to those of the original big bang nucleosynthesis, or would they just fall apart and form 4He? Another problem is that I've only recently begun to understand what a triple product is but I cant' find them for any of the "stellar" nuclear processes, only typical processes like deuterium-tritium and so on.
