39K(p,γ)40Ca paper accepted for publication!

Our paper exploring the current experimental information on the 39K(p,γ)40Ca reaction cross section was just accepted in Physical Review C! This reaction is critical for explaining the peculiar elemental abundance patterns in the Globular Cluster NGC 2419, which can help us understand how the galaxy evolved. We found that inconsistencies in cross section measurements make the uncertainty in this rate larger than previously assumed, thus further exeperimental efforts should be aimed at investigating the 39K(p,γ)40Ca cross section.
