摘要：This manuscript reviews recent progress in our understanding of the nucleosynthesis of medium
and heavy elements in supernovae. Recent hydrodynamical models of core-collapse supernovae
show that a large amount of proton rich matter is ejected under strong neutrino fluxes. This
matter constitutes the site of the n p-process where antineutrino absorption reactions catalyze
the nucleosynthesis of nuclei with A > 64. Supernovae are also associated with the r-process
responsible for the synthesis of the heaviest elements in nature. Fission during the r-process can
play a major role in determining the final abundance patter and in explaining the almost universal
features seen in metal-poor r-process-rich stars.
