Experimentally constrained (p, γ)89Y and (n, γ)59Y reaction rates relevant to p-process nucleosynthesis

NUCLEAR REACTIONS 89Y(p, p'γ), E=17 MeV; measured E(p), I(p), Eγ, Iγ, γ(θ), pγ-coin using silicon ring (SiRi) array for protons and CACTUS array for γ rays at OSLO cyclotron facility; deduced level density, normalized γ-strength function (γSF) of 89Y, enhancement of γSF due to strong, low-energy M1 transitions at high excitation energies. Comparison with shell-model calculations. 88Sr(p, γ)89Y, E=1.5-5 MeV; 88Y(n, γ)89Y, E=0.01-1.5 MeV; deduced cross sections and astrophysical reaction rates using present data and TALYS code. Comparison of cross-section data with values from the BRUSLIB library. Relevance to p-process nucleosynthesis.
