| Abstract: | The neutron capture cross sections of 93Nb, 169Tm, 181Ta, Ag, Hf and W were measured with respect to that of 197Au in the energy range from 10 to 100 keV using the time-of-flight method. Kinematically collimated neutrons were produced via the 7Li(p, n)7Be reaction. Capture events were detected with two Moxon-Rae detectors.The results were compared with the data from other authors. |
