2020, Progress in Nuclear EnergyCitation Excerpt :In addition, calculations were performed by using cross section data taken from JENDL/AN-2005 library (Murata et al., 2006) and precompiled data libraries of the SOURCES4C code. Among cross section data in the SOURCES4C and ORIGEN libraries, those concerning α-particle interactions with oxygen are based on Bair's thin- and thick-target measurements (Bair and Willard, 1962; Bair and Haas, 1973; Bair and Gomez del Campo, 1979) for the lower-energy and on Hansen's data (Hansen et al., 1967) for the high-energy range. Table 2 lists the selected set of measured and calculated data for the total neutron yield for different oxide matrix sources used to test the performance of the different cross section libraries.

2016, Progress in Nuclear EnergyCitation Excerpt :As recommended in Ref. (Bair et al., 1979), this accurate measurement was used to normalize the thin-target 17,18O(α,n) cross-section data. As in the SOURCES4C data libraries, the same data for natO(α,n) were also used to adjust the high-energy 17,18O(α,n) cross section measurements of Hansen (Hansen et al., 1967) by a 9.2% reduction, resulting from the integral data for natO(α,n) over the range 5.15≤Eα≤ 8 MeV (Bair et al., 1979). In Fig. 5, one can see that, as the energy increases, the resonance-like structure derived from Bair's experiments is replaced by a smooth, averaged behavior, yielding a cross section with broad fluctuations.
