Abstract :
In order to provide thin-target cross sections as a basis for model calculations of the interactions of solar and galactic α-particles, irradiation experiments with α-particles were performed at the injector cyclotron at PSI/Villigen (Emax = 119.7 MeV) and at the isochronous cyclotron JULIC at KFA Jülich (Emax = 170.5 MeV). The stacked foil technique was used to investigate residual nuclide production from C, N, O, Mg, Al and Si. The product nuclides 7Be, 22Na, 24Na and 28Mg were measured by γ-spectrometry, 10Be and 26Al by accelerator mass spectrometry. The new data are compared with earlier measurements and analyzed using hybrid model of preequilibrium reactions.
