Resonance analysis of the {sup 12}C,{sup 13}C({alpha},n) reactions and evaluation of neutron yield data of the reaction Murata, Toru [AITEL Corp., Tokyo (Japan)] 66 PHYSICS; CARBON 12 TARGET; CARBON 13 TARGET; ALPHA REACTIONS; MEV RANGE 01-10; MEV RANGE 10-100; RESONANCE; R MATRIX; NEUTRON SPECTRA; CROSS SECTIONS; OPTICAL MODELS; COMPUTERIZED SIMULATION; THEORETICAL DATA The {sup 12}C({alpha},n){sup 15}O reaction and the {sup 13}C({alpha},n){sup 16}O reaction were analyzed with a resonance formula in the incident {alpha}-particle energy range of 1.0 to 16.0 MeV. With the obtained resonance parameters, branching ratios of the emitted neutrons to the several levels of the residual nucleus and their angular distributions were calculated to obtain the energy spectrum of emitted neutrons. Thick target neutron yield of carbon were also calculated and compared with the experimental data.
