First direct measurement of 59Cu(p, α)56Ni: step towards constraining the Ni-Cu cycle in the cosmos

NUCLEAR REACTIONS 1H(59Cu, α)56Ni, E=8.5 MeV/nucleon, [secondary 59Cu beam from Nb(p, X), E=480 MeV at the TRIUMF cyclotron, followed by re-acceleration of 59Cu beam by ISAC-II superconducting LINAC, solid H2 target]; measured protons and α particles, angle-integrated σ using thick single-sided silicon strip detectors and a layer of thick CsI(Tl) detectors; deduced ratio of integrated σ to total σ, exclusive population of the ground state of 56Ni in (p, α). Comparison with Hauser-Feshbach based statistical model calculations; deduced overestimation of (p, α) cross section in this region. Discussed impact on νp process and x-ray bursts (XRBs). Relevance to Ni-Cu cycle in nucleosynthesis, with competing 59Cu(p, α)56Ni and 59Cu(p, γ)60Zn reactions.
