GALACTIC CHEMICAL EVOLUTION: THE IMPACT OF THE 13C-POCKET STRUCTURE ON THE s-PROCESS DISTRIBUTION [PDF]
, 2017 The solar s-process abundances have been analyzed in the framework of a Galactic Chemical Evolution (GCE) model. The aim of this work is to implement the study by Bisterzo et al., who investigated the effect of one of the major uncertainties of ...

S stars and s-process in the Gaia era [PDF]
Astronomy & Astrophysics, 2018 Context. S stars are transition objects between M-type giants and carbon stars on the asymptotic giant branch (AGB). They are characterized by overabundances of s-process elements.

A Brief Review of the s-process of Nucleosynthesis [PDF]
Symposium - International Astronomical Union, 1991 A brief overview is presented of the s-process of nucleosynthesis. Special emphasis is put on some of its nuclear physics aspects, and in particular on the uncertainties that still affect the rates of the 13C(α,n)16O and 22Ne(α,n)25Mg neutron producing reactions.

The Astrophysical Journal, 1967 The nucleosynthesis of heavy stable nuclei by successive captures of neutrons in a weak neutron flux (the s-process) is terminated at large atomic weight by alpha decay to isotopes of lead. We analyze the details of this termination and calculate the abundances of lead and bismuth isotopes synthesized by the exposure of lighter nuclei to neutrons.

Photoneutron cross sections for Ni isotopes: Toward understanding (n,γ) cross sections relevant to weak s -process nucleosynthesis [PDF]
Physical Review C, 2018 Photoneutron cross sections were measured for $^{58}$Ni, $^{60}$Ni, $^{61}$Ni, and $^{64}$Ni at energies between the one-neutron and two-neutron thresholds using quasi-monochromatic $\gamma$-ray beams produced in laser Compton-scattering at the NewSUBARU
