【 摘 要 】

We have aroundninety chemical elements available in nature, which were produced mainly bynuclear reactions inside stars. The fusion reactions are the main synthesisprocess which generates the light and intermediate masses elements. The synthesisbegins with the hydrogen burning reaching the region of iron mass nuclei. Heavierelements are synthesized by neutron capture processes, forming exotic nucleiwith large neutron excess. These systems present characteristics very differentfrom nuclei inside of stable atoms; they only occur in particular astrophysicalenvironments or are produced artificially in special laboratory conditions.This work discusses some properties of the exotic nuclei and how they participatein the synthesis of elements.
