between TOF spectra with only
nat U (blue line) and the mixture (red line) (Fig. 3.8).
This result indicates that the self-indication TOF spectrum was not greatly
influenced by nuclide impurity. It was experimentally shown that the contribution
from the other nuclide can be remarkably suppressed by applying the selfindication method.
