Experimental partial and total kerma coefficients for aluminium at incident neutron energies from reaction thresholds to 65 MeV

For nine incident neutron energies in the range 25 to 65 MeV, the double-di fferential cross sections (energy spectra) for the (n, px), (n, dx), (n, tx ) and (n, alpha x) reactions on aluminium have been measured at lab angles between 20 degrees and 160 degrees in steps of 10 degrees. The partial and total kerma coefficients have been determined from the experimental energy- differential cross sections. The resulting partial kerma coefficients for t he incident neutron energy range of 25-65 MeV are extrapolated to the thres hold energy of each registered reaction product type. Only illustrative res ults of the experimental double-differential, energy-differential and total cross sections are presented. The deduced partial and total kerma coeffici ents of the present work are compared with results of previous integral mea surements and theoretical predictions.
