A new evaluation of 17O system is made. The reaction channels includes:
'16O(N,N0)16O0 ' '16O(N,4HE)13C0 ' '16O(N,N1)16O1 '
'16O(N,N2)16O2 ' '16O(N,N3)16O3 ' '16O(N,N4)16O4 '
'16O(N,4HE1)13C1 ' '16O(N,4HE2)13C2 ' '16O(N,4HE3)13C3 '
'13C(4HE,4HE)13C0' '13C(4HE,N0)16O0 ' '13C(4HE,N1)16O1 '
'13C(4HE,N2)16O2 ' '13C(4HE,N3)16O3 ' '13C(4HE,N4)16O4 '...
A $^{16}$O(n,$\alpha$)$^{13}$C reaction cross section measurement was carried out at the time-of-flight facility GELINA using a Frisch-grid ionization chamber built by HZDR. Between the reaction threshold (2.36 MeV) and a neutron energy of 9 MeV, $^{16}$O(n,$\alpha_0$)$^{13}$C events could be separated well from background events.
The experimental $^{16}$O(n,$\alpha_0$)$^{13}$C data are...
The angular dependence of the differential cross-sections for the 13C(α,n0)16O reaction was measured in the energy range of 2.0-6.2 MeV using the time-of-flight method for separating neutrons corresponding to the ground state of the residual nucleus. The integrated total cross-sections were derived from the measured data and the cross-sections for the 16O(n,α0)13C reaction were determined...
Oxygen is present in many materials - water, oxides, concrete and elsewhere - and the uncertainties in its nuclear data can have a significant impact on many nuclear applications. The current status of the oxygen-16 data is a 30-50 % discrepancy among various $^{16}$O(n,$\alpha$) and $^{13}$C($\alpha$,n) cross section measurements. Reconciling these discrepancies and settling on a best value...
Improved $(\alpha,n)$ cross section measurements are needed for a range of applications such as nuclear astrophysics, neutrino physics, geophysics, nuclear energy, and weapons research. While they are sometimes focused on different energy regions, all benefit from a improved measurements over a wide energy range. The connection is further strengthened through the use of $R$-matrix analysis for...
A brief overview of the R-matrix evaluation method implemented in EDAf90 that emphasizes the relativistic model parametrization, polarization capabilities, and computational capabilities. We will review existing evaluations for (alpha,n) on material targets n, 1H, 2H, 3H, 3He, 6Li, 7Li, 11B (time permitting) and discuss recent activity on 13C in the 17O system analysis.
