This report describes the analysis of the measurement of the 232Th(n,g) reaction, performed at nTOF-CERN in 2002. The analysis procedure to obtain the capture yield is detailed and the resulting cross section in the unresolved resonance region up to 1 MeV is given. The obtained cross section is independent from a reference capture measurement because of the self-normalization by means of a saturated resonance at low neutron energy. To check the analysis procedure, we performed identical steps for a gold sample measured in the same conditions. This measurement is part of experiment TOF07 [1]. |
