Double differential cross section measurements of the (n,px), (n,dx), (n.tx) and (n,αx) reactions on 12C: kerma determination at energies between 30 and 75 MeV

The double-differential cross sections for the (n,px), (n,dx), (n,tx) and (n,αx) reactions on carbon have been measured at 42.5, 62.7 and 72.8 MeV incident neutron energies at laboratory angles from 20o to 160o in 10o steps. The energy differential cross sections are deduced and consequently the partial and total kerma values. Experimental results are compared with existing data and theoretical calculations. Preliminary results on carbon are also shown concerning the light charged particle spectra induced by neutrons from the low energy tail of the incident neutron spectrum. (author)
