Investigation of alpha-induced reactions on Ba-130 and Ba-132 and their importance for the synthesis of heavy p nuclei
(2012-02-17)
Captures of a particles on the proton-richest barium isotope, Ba-130, have been studied in order to provide cross-section data for the modeling of the astrophysical gamma process. The cross sections of the Ba-130(alpha,g ...
Reaction rate sensitivity of Ti-44 production in massive stars and implications of a thick target yield measurement of Ca-40(alpha, gamma)Ti-44
(2010-06-01)
We evaluate two dominant nuclear reaction rates and their uncertainties that affect Ti-44 production in explosive nucleosynthesis. Experimentally we develop thick target yields for the Ca-40(alpha, gamma)Ti-44 reaction at ...
