Estimation of neutron cross-sections for $$^{16}$$O up to 5.2 MeV through R-matrix analysis

Kunieda, Satoshi ; Kawano, Toshihiko*; Paris, M.*; Hale, G. M.*; Shibata, Keiichi; Fukahori, Tokio 

There still remain differences among measured data, which makes the evaluated cross-sections uncertain, and which consequently affects some integral calculation. $$^{16}$$O is one of the important nuclei in the nuclear application, but such kinds of issues appears in elastic-scattering and (n,$$alpha$$) reaction cross-sections. Purpose of this study is to solve those issues as they are common concerns in the world. We present estimated cross sections and their covariance data which are "physically" constrained by the R-matrix theory. The differences between the estimated and the measured cross-sections will be also discussed.
