Neutron Capture Cross Sections for the Weak s Process [PDF]
, 2009 In past decades a lot of progress has been made towards understanding the main s-process component that takes place in thermally pulsing Asymptotic Giant Branch (AGB) stars.

The Astrophysical Journal, 1972 We calculate the overabundances of rare neutron-rich species produced when seed nuclei between silicon and nickel are exposed to small neutron irradiations in order to ascertain whether those species may owe their natural abundances to such a cause, Particular attention is given to 54Cr and 58Fe, two relatively prominent neutron-rich species that have ...

The effect of 12C + 12C rate uncertainties on s-process yields [PDF]
, 2010 The slow neutron capture process in massive stars (the weak s-process) produces most of the s-only isotopes in the mass region 60 < A < 90. The nuclear reaction rates used in simulations of this process have a profound effect on the final s-process ...

News from the p-process: is the s-process a troublemaker? [PDF]
, 2000 The most detailed calculations of the p-process call for its development in the O/Ne layers of Type II supernovae. In spite of their overall success in reproducing the solar system content of p-nuclides, they suggest a significant underproduction of the ...

Abundances of s-process elements in planetary nebulae: Br, Kr & Xe [PDF]
, 2006 We identify emission lines of post-iron peak elements in very high signal-to-noise spectra of a sample of planetary nebulae. Analysis of lines from ions of Kr and Xe reveals enhancements in most of the PNe, in agreement with the theories of s-process in ...
