Nuclide production by proton-induced reactions on elements (6 <= Z <= 29) in the energy range from 200 MeV to 400 MeV

In the course of a systematic investigation of integral cross sections for nuclide production by proton-induced reactions, irradiation experiments were carried out with proton energies of 300 and 400 MeV at the Laboratoire National Saturne, Saclay, France using the stacked-foil technique. We included 19 different target elements with atomic numbers between 6 and 79 (C, N, O, Mg, Al, Si, Ca, Ti, Mn, Fe, Co, Ni, Cu, Sr, Y, Zr, Nb, Ba and Au) in our experiments, of which we report here results up to Z = 29. Residual nuclides were measured by γ-spectrometry and by accelerator mass spectrometry (AMS). Corrections of the cross sections for reactions of interfering secondary particles between 5% and 30% had to be made. Results from thin targets placed in front of the stacks, for which no contributions of secondaries occured, are in excellent agreement with the ones from targets inside the stacks after correction. About 700 cross sections for 114 reactions were measured. The new data show excellent consistency with the earlier measurements of our group below 200 MeV and above 400 MeV. The now existing data base of experimental excitation functions for the production of short-lived and some long-lived radionuclides relevant for cosmic ray interactions with extraterrestrial and terrestrial matter, i.e. ¹⁰Be, ²⁶Al, and ³⁶Cl, is discussed in detail. The experimental data are compared with theoretical ones based on calculations using an INC/E model and on the hybrid model of preequilibrium reactions.
