Description
Info about main s-process
The 13C(α,n)16O reaction is the main neutron sources for the weak s-process, responsible for the nucleosynthesis of about half of the elements heavier than iron. It takes place in thermally pulsing low mass AGB stars at about 90 MK, corresponding to a Gamow window between 140 - 230 keV. These energies are well below the Coulomb barrier. In last decades several direct and indirect measurements...
More than ∼ 50% of nuclei with A ≥ 56 are produced by the s-process [1], a succes-sion of neutron captures slower than β-decay rates, constraining the nucleosynthesis path close to the stability valley. The neutron source feeding the s-process has been identified in the 13C(α, n)16O reaction taking place in asymptotic giant branch (AGB) stars. In this contribution, I will focus on the indirect...
