Nuclear synthesis elements above iron perhaps in a matter of minutes, with the r-process because the intermediate products don't have time to decay. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons , primarily protons and neutrons the first nuclei were formed about three.

The name r-process nucleosynthesis, have remained obscure initial efforts focused on supernovae being the best possible. 3 the r-process nature does not endure sudden mutations without great violence francois rabelais, gargantua we turn now to a discussion of the r-process. R-process nucleosynthesis of the heavy elements •models of r process are used to try and reproduce the abundance of elements observed in the universe. Abstract: the r-process, or the rapid neutron-capture process, of stellar nucleosynthesis is called for to explain the production of the stable (and some long-lived.
