Experimental partial and total kerma coefficients for carbon deduced from microscopic cross sections at incident neutron energies below 75 MeV

Abstract

The double-differential cross sections for proton, deuteron, triton and alpha particle production in fast neutron induced reactions on carbon have been measured at several neutron energies from 25 to 75 MeV in the angular range from 20° to 160°. Experimental energy-differential, angle-differential and total cross sections are deduced, and consequently the partial and total kerma coefficients. The obtained experimental partial kerma coefficients are extrapolated down to the threshold energy of each measured reaction channel. Results on the experimental double-differential, energy-differential and total cross sections are briefly presented. The deduced partial and total kerma coefficients of the present work are compared with previous measurements and theoretical predictions.
