Production cross sections of Rh and Ag in proton bombed Pb target with 400 MeV energy.

The accelerator-driven subcritical system (ADS) is a competitive option for next-generation nuclear energy systems. Production cross sections of long-lived residual radioactive nuclides in a proton-nuclide reaction are basic quantities for the calculation of accumulated radioactivity in the use of ADS systems. This work presents the production cross sections of Rh and Ag in a natural lead (Pb) target activated by 400 MeV protons.

Theoretical simulation of residual nuclide products in 208,207,206Pb, NATPb and 209Bi (P,X) reactions at intermediate and high energies.

The independent and cumulative measured yields of residual products in thin lead and bismuth targets irradiated with 0.04-2.6 GeV protons are compared with results by the LAHET, CEM03, LAQGSM03, INCL+ABLA, CASCADE and YIELDX codes, in order to evaluate the predictive power of the codes in this energy region.

MENDL2 and IEAF2001 nuclide production yields databases verification in inter-medium energy range.

This work presents results of computer simulation of two experiments which aim at measuring the threshold activation reaction rates in 12C, 19F, 27Al, 59Co, 63Cu, 65Cu, 64Zn, 93Nb, 115In, 169Tm, 181Ta, 197Au, and thin samples placed inside and outside a 0.8 GeV proton-irradiated 4-cm thick W target and a 92-cm-thick W-Na composite target of 15 cm diameter both. In total, more than 1000 values of activation reaction were determined in both the experiments.
