From the HINDAS Project: Excitation Functions for Residual Nuclide Production by Proton-Induced Reactions

Abstract

Abstract.A survey is given about efforts undertaken during the HINDAS project to investigate the energy dependence of residual nuclide production by proton-induced reactions from thresholds up to 2.6 GeV. For proton-induced reactions, our experiments aimed to further developing and completing the cross section database which was established by our collaboration in recent years. It was extended to the heavy target elements Ta, W, Pb, and Bi for energies up to 2.6 GeV. In addition, new measurements for the target element iron were performed up to 2.6 GeV and for natural uranium for energies from 21 MeV to 69 MeV. For the target element lead, a comprehensive set of excitation functions published recently was completed by AMS-measurements of cross sections for the production of the long-lived radionuclides Be-10, Al-26, Cl-36, and I-129 and by mass spectrometric measurements for stable and radioactive rare gas isotopes of He, Ne, Ar, Kr, and Xe. Comprehensive tests of the nuclear reaction codes TALYS and INCL4+ABLA, which were developed within the HINDAS project, were performed with the new experimental results over the entire energy range.

Potential of AMS for Quantifying Long-Lived Reaction Products

“…A variety of nuclear data request lists exist (e.g., from the NEA [13]). Large-scale nuclear data programs are, e.g., HINDAS for cross-section measurements in the 20-200 MeV energy region and beyond on Fe, Pb, U [14][15][16], applying partly the AMS technique too (see also [17,18]). Another somewhat competing program is n-TOF [19] for cross sections measurements from 1 eV to 250 MeV.…”

A study of proton-induced reactions on natural Silicon targets

“…In the present work, we study the bombardment energy dependence of isotope production in proton-induced reactions on a natural silicon target. Experimental data consist of 7 excitation functions of isotopes produced in the p + nat Si reaction [1,2]. Comparisons are made with the predictions of the nuclear reaction program TALYS 1.95 [2], semi-empirical formulas of Silberberg-Tsao (code yieldx) [3], SPACS [4] and previously published results of code ALICE [5].…”
