Because the separation was difficult on the entire energy range; the reported cross-sections in the present work for α-particles include the 3 He events. Nevertheless; their contribution is much smaller than that of 4 He; being within the experimental errors. This conclusion is also supported by the theoretical calculations;

摘要：

14 Experimental double-differential cross-sections (d(2)sigma/dOmegadE) for fast neutron-induced proton, deuteron, triton, and alpha-particle emission on Fe-nat, Co-59. Bi-209, and U-nat are reported at several incident neutron energies between 25 and 65MeV for outgoing particle energies above the experimental energy detection thresholds. Angular distributions were measured at laboratory angles between 20degrees and 160degrees. Reliable extrapolated spectra were obtained at very forward (2.5degrees and 10degrees) and at very backward (170degrees and 177.5degrees) angles. Based on these experimental data, energy-differential (dsigma/dE), angle differential (dsigma/dOmega), and total cross-sections (UT) are reported for each detected particle species.
