TL;DR: In this paper, the authors have made new, improved measurements of the Si28-30 (n, gamma) cross sections and have done a resonance analysis of these data including previous total cross sections.

TL;DR: This paper measured the cross section from 3 eV to 500 keV to test nuclear statistical models which must be relied on to calculate the rates for as yet unmeasurable reactions occurring in explosive nucleosynthesis scenarios and found that their data are in reasonably good agreement with the reaction rate predicted by an older model but that the rates predicted by two very recent models are roughly a factor of 3 different from the data (in opposite directions).

TL;DR: A reaction network code was used to explore the changes in the calculated isotopic abundances resulting from the new reaction rates for an {ital s}-process scenario based on a stellar model, evidence for the need for more sophisticated models of the {ital S} process beyond the classical model.

TL;DR: In this article, the authors made new and improved measurements of the neutron capture and total cross sections for Sr-88 at the Oak Ridge Electron Linear Accelerator (ORELA).

TL;DR: The neutron capture cross sections of proton magic tin isotopes were measured for a discussion of the solar tin abundance and for an improved determination of the isotopic {ital s}- and {ital r}-process components.
