First direct measurement of Cu59(p,α)Ni56: A step towards constraining the Ni-Cu cycle in the cosmos
Abstract
Reactions on proton-rich nuclides drive the nucleosynthesis in core collapse supernovae (CCSNe) and in x-ray bursts (XRBs). CCSNe eject the nucleosynthesis products to the interstellar medium and hence are a potential inventory of p nuclei, whereas in XRBs nucleosynthesis powers the light curves. In both astrophysical sites the Ni-Cu cycle, which features a competition between Cu59(p,α)Ni56 and Cu59(p,γ)Zn60, could potentially halt the …
