4. Conclusions
The values of the neutron capture cross-section of 232 Th that were measured in the present work
are in agreement with the JENDL database up to 800 keV and over 1.4 MeV. For energies in the
intermediate range, values are slightly lower to all the databases but in agreement with the most recent
values of Davletshin et al., [11]. Moreover, a re-normalisation of 232 Th and 238 U neutron capture data
of Lindner et al., [12] (the most reliable considered data and the basis of many evaluations) with 238 U
from the current ENDF and JENDL databases was undertaken (Figure 3b). The later reveals that a
very good agreement is reached with the data of the present work, data from a time of flight
experiment that were the basis for the JENDL evaluation [13] and data that could be the basis of a new
BROND or ENDF evaluation [11,12].
