Experimental double-differential cross sections and derived kerma factors for oxygen at incident neutron energies from reaction thresholds to 65 MeV

The double-differential cross sections (energy spectra) for the (n, px), (n , dx), (n, tx) and (n, alpha x) reactions on oxygen have been measured for nine incident neutron energies in the range 25 to 65 MeV at lab angles betw een 20 degrees and 160 degrees in steps of 10 degrees. From these measureme nts, the energy differential cross sections have been determined and conseq uently the partial and total kerma factors. Based on the obtained experimen tal partial kerma factors in the incident neutron energy range 25-65 MeV, a procedure is proposed for the extrapolation of these values to the reactio n threshold energy of each measured reaction channel. Results of the experi mental double-differential, energy differential and total cross sections ar e presented. The deduced partial and total kerma factors of the present wor k are compared with results of previous measurements and theoretical predic tions.
