Abstract we calculate the nucleosynthesis inside the hot bubble formed in the jittering‐jets model for core‐collapse supernova explosions, and find the format. The r-process and the s-process contribute roughly equally to the nucleosynthesis of heavy isotopes the elements that compose the materials of the solar system. 1 introduction the r-process, or the rapid neutron-capture process, of stellar nucleosynthesis is invoked to explain the production of the stable (and some long.
Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons , primarily protons and neutrons the first nuclei were formed about three.
