Light-ion production in the interaction of 96 MeV neutrons with carbon

Abstract

Double-differential cross sections for light-ion (p, d, t, 3He and alpha) production in carbon induced by 96 MeV neutrons have been measured at eight laboratory angles from 20 degrees to 160 degrees in steps of 20 degrees. Experimental techniques are presented as well as procedures for data taking and data reduction. Deduced energy-differential, angle-differential and production cross sections are reported. Experimental cross sections are compared with theoretical reaction model calculations and experimental data in the literature. The measured particle data show marked discrepancies from the results of the model calculations in spectral shape and magnitude. The measured production cross sections for protons, deuterons, tritons, 3He, and alpha particles support the trends suggested by data at lower energies.Comment: 40 pages, 18 figures, 3 table

Measurement of Muon Antineutrino Quasielastic Scattering on a Hydrocarbon Target atEν∼3.5 GeV

“…The systematic error on the recoil energy measurement is due to the uncertainty in the MINERvA detector energy scale set by muons and differences between the simulated calorimetric response to single hadrons and the response measured by the test beam program. Additional uncertainties are due to differences between the Geant model of neutron interactions and thin target data on neutron scattering in carbon, iron and copper [39][40][41][42][43][44][45][46]. We evaluate further sources of systematic error by loosening analysis cuts on energy near the vertex and on extra isolated energy depositions, repeating the fit to the background and subsequent analysis, and assigning an uncertainty to cover the difference.…”

Production of protons, deuterons, and tritons from carbon bombarded by 175 MeV quasi mono-energetic neutrons

“…Data analysis procedure based on the E-E particle identification technique is basically same as in the previous measurements at 96 MeV [4][5][6][7] . Figure 2 shows an example of two-dimensional scatter plots of pulse height signals from two E detectors ( E 1 and E 2 ) located at 20 degrees.…”

“…1,2) . Quasi-monoenergetic neutrons generated by using the 7 Li(p,n) 7 Be reaction irradiated a 1mm-thick carbon target 22 mm in diameter. Energy and angular distributions of neutron-induced light-ion production yields from carbon were measured with the MEDLEY setup shown in Fig.1.…”

Experiments and Theoretical Data for Studying the Impact of Fission Yield Uncertainties on the Nuclear Fuel Cycle with TALYS/GEF and the Total Monte Carlo Method

“…For this, we will use the white neutron beam that is to be produced via the C(d,n) reaction and will allow accessing a neutron energy region stretching from about 1 to 30 MeV. The measurements are planned with an upgraded version of Medley [15,16] which will include PPAC detectors with good time resolution to determine the energy of the neutrons impinging on the sandwich target. The target is planned to consist of three layers: 235 U, CH 2 , and 238 U.…”
