Evaluated cross-section data files were prepared for the stable tungsten isotopes with the objective to provide reliable and sound nuclear data for activation and inventory calculations of the European Spallation Source (ESS) which utilizes a tungsten target irradiated by 2.5 GeV protons. The data files contain yields of radionuclides produced by proton induced reactions with incident energies up to 3 GeV. The data were obtained from the analysis of calculations using advanced nuclear models,

... ailable experimental data and systematics. The calculations of cross-sections were performed using the intranuclear cascade model, the pre-equilibrium exciton model, and the Hauser-Feshbach model. The available experimental information, results of calculations and systematics were applied for the evaluation of yields of residual nuclei using statistical methods implemented in the computer code package BEKED developed at KIT. ii iii CONTENTS page
