“…Full curves in figure 7 are results based on microscopic cross sections calculated with the nuclear data code GNASH in the energy range 20 to 80 MeV (Chadwick et al 1999). The calculations describe well the experimental kerma coefficients for deuterons but underestimate them for protons.…”

“…The model includes alpha clustering and particle pick-up, uses the Fermi breakup mechanism, and allows decay via intermediate particle-unstable states (Brenner and Prael 1989). The continuous lines present the GNASH nuclear data code calculations (Chadwick et al 1999). The GNASH code uses the exciton model and Hauser-Feshbach theory for sequential equilibrium decay (Young et al 1992) and includes direct inelastic scattering contributions.…”

“…Considering all extrapolated lab angles, a constant double-differential cross section equal either to the value at the highest measured angle, or to a zero value, two limits are obtained which are within the uncertainties of the energy-differential cross sections in figures 5 and 6. (Chadwick et al 1999) as full curves. The proton spectra are rather well described, despite a slight underestimation at lower neutron energies.…”

“…In this interval the alpha-particle production total cross sections do not show a decrease towards the threshold (6.2 MeV). Therefore, theoretical values from Chadwick et al (1999) were used to extrapolate the total cross sections down to 20 MeV incident neutron energy. For neutron energies lower than 20 MeV, ENDF/HE-VI data for 12 C(n, αx) reactions were used.…”

“…For neutron energies lower than 20 MeV, ENDF/HE-VI data for 12 C(n, αx) reactions were used. The parametrization of the alpha-particle total cross sections σ T = p √ E n − E th was applied to data for neutron energies between 15 and 20 MeV and the extrapolated alpha-particle kerma coefficients were normalized to the corresponding theoretical kerma coefficients from Chadwick et al (1999).…”

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

et al. 2000

View full text Add to dashboard Cite

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 degrees to 160 degrees. 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.
