KERMA VALUES DEDUCED FROM NEUTRON-INDUCED CHARGED-PARTICLE SPECTRA OF CARBON FROM 40-MEV TO 75-MEV

The double-differential cross-sections for the C-12(n, px), C-12(n, dx), C-12(n, tx) and C-12(n, alpha x) reactions have been measured at three incident neutron energies, 42.5, 62.7 and 72.8 MeV, at laboratory angles between 20 degrees and 160 degrees. From these measurements, the energy-differential cross-sections have been determined and consequently the partial and total kerma values. Results of the experimental double-differential and energy-differential cross-sections at the three incident neutron energies are presented. The deduced kerma values are compared with previous measurements and theoretical predictions.
