Résumé : The proton capture reactions 89Y(p,γ)90Zr and 88Sr(p,γ)89Y have been investigated at energies Ep = 1.5-3.5 MeV via an array of 4 HPGe detectors of ≈100% rel. efficiency. The resulting cross sections as well as the existing data on the 90Zr(p,γ)91Nb and 92Mo(p,γ)93Tc reactions are compared with improved statistical model calculations carried out using the MOST code.
