[en] Experimental double-differential cross sections (d²σ/dΩdE) for fast neutron-induced proton, deuteron, triton, and alpha-particle production on aluminum are reported, at several incident neutron energies between 25 and 65 MeV, for outgoing particle energies above the experimental energy thresholds. Angular distributions were measured at laboratory angles between 20 deg. and 160 deg. . Reliable extrapolated spectra are derived for very forward (2.5 deg. and 10 deg. ) and very backward angles (170 deg. and 177.5 deg. ). Based on these experimental data, energy-differential (dσ/dE), angle-differential (dσ/dΩ), and total production cross sections (σ_T) are reported for each outgoing particle

Angular distributions were measured at 15 laboratory angles between 20 deg. and 160 deg. Procedures for data taking and data reduction are shortly presented. Deduced energy-differential, angle-differential and total cross sections are also reported. Experimental cross sections are compared with existing experimental data and with theoretical model calculations

[en] Experimental double-differential cross-sections (d²σ/dΩ dE) for fast neutron-induced proton, deuteron, triton, and α-particle emission on ^natFe, ⁵⁹Co, ²⁰⁹Bi, and ^natU are reported at several incident neutron energies between 25 and 65 MeV for outgoing particle energies above the experimental energy detection thresholds. Angular distributions were measured at laboratory angles between 20 deg. and 160 deg. Reliable extrapolated spectra were obtained at very forward (2.5 deg. and 10 deg.) and at very backward (170 deg. and 177.5 deg.) angles. Based on these experimental data, energy-differential (dσ/dE), angle differential (dσ/dΩ), and total cross-sections (σ_T) are reported for each detected particle species

[en] The double-differential cross sections for the ¹²C(n,px), ¹²C(n,dx), ¹²C(n,tx) and ¹²C(n, αx) reactions have been measured at three incident neutron energies, 42.5, 62.7 and 72.8 MeV, at laboratory angles between 20^o and 160^o. 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. (Author)

[en] Experimental results concerning light charged particle (proton, deuteron, triton and α-particle) production in fast neutron induced reactions on bismuth are reported for several incident neutron energies between 25 and 65 MeV. Energy spectra (double-differential cross sections) were measured at 9 laboratory angles between 20 deg. and 160 deg. and extrapolated and interpolated to other 10 angles. The experimental set-up and procedures for data reduction including corrections and normalisation are shortly presented and discussed. Resulting energy-differential and total cross sections are reported as well. Experimental cross sections are compared to similar available data from neutron and proton induced reactions. Theoretical calculations are based on GNASH and TALYS nuclear reaction codes which integrate the optical model, direct, pre-equilibrium, fission and statistical nuclear reaction models in one calculation scheme

[en] 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 20^o to 160^o in 10^o 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)

[en] The activation of ¹⁰⁵Ag(T_1/2=41 d) via the ¹⁰⁷Ag(n, 3n) and the ¹⁰⁹Ag(n, 5n) reactions has been investigated in quasi-monoenergetic neutron beams with mean energies of 27, 31, 38, 39, 60 and 64 MeV. The activity of ¹⁰⁵Ag was determined by using calibrated Ge detectors. The relative spectral fluences of the neutron beams were measured by applying time-of-flight techniques on scintillation detectors. The absolute fluences were determined with a proton recoil telescope. The fluence-weighted mean cross sections were 780(75), 820(50), 550(50), 530(50), 540(100) and 590(70) mb. The excitation function was derived with an unfolding procedure applied on the mean cross sections measured and on the spectral neutron fluences. (orig.)
