Based on activation measurements with W targets of natural isotopic abundance, the cross sections for thermal neutron capture by W and W have been determined by comparing the activities of W and W after activation with that of W. Relative to the known cross sections for capture by W, after correction of the latter for changes in the recommended γ-ray branching intensities, the values of the thermal cross sections have been determined to be 22.7(16) b for capture by W and 1.60(11) b for W. The half-life of W was re-determined to be 23.80(3) h.
