Impact of the latest 22Ne+α reaction rates on nucleosynthesis in massive stars and galactic chemical evolution
Emma Kotar, Shuya Ota, Allyson Dewey +3
In massive stars (initial mass of > 9 solar masses), the weak s (slow neutron capture) process produces elements between Fe and Zr, enriching the Galaxy with these elements through…
Constraining capture cross sections using proton inelastic scattering as a surrogate reaction
Aaina Thapa, Jutta Escher, Emanuel Chimanski +6
The surrogate reaction method is an alternative to direct measurements of compound nuclear reaction cross sections. We introduce theory tools for extracting capture cross sections…
The Ne(,n)Mg reaction -- state of the art, astrophysics, and perspectives
Andreas Best, Philip Adsley, Ryan Amberger +11
One of the most important stellar neutron sources is the Ne(,n)Mg reaction, which gets activated both during the helium intershell burning in asymptotic giant bra…
First experimental test of the ratio method for nuclear-reaction analysis
S. Ota, P. Capel, G. Christian +9
Nuclear halos are very exotic quantal structures observed far from stability. Because of their short lifetime, they are mostly studied through reactions. The ratio method offers a…
First Experimental Test of the Ratio Method
S. Ota, P. Capel, G. Christian +9
The ratio is a new reaction observable suggested to extract accurately structure information on halo nuclei. It corresponds to the ratio of differential cross sections for scatteri…
