Abstract

We have observed the excitation of the 7.65 MeV level (0⁺) in the inelastic scattering of 14 MeV neutrons from ¹²C. The angular distribution gives a strong forward maximum σ(θ) ≈ 8 mb/sr at θ = 20° (about 0.1 of the 4.43 MeV level excitation cross section). The simple Bessel-function distribution j₀²(kR), with R ≈ 5.4 fm for the nuclear interaction radius, agrees, at first sight with data (except at wide angles) suggesting a direct-interaction process (α-cluster excitation).

Experimental differential cross sections are also presented for elastic scattering and for the 4.43 and 9.63 MeV levels.

Partial cross section determination of the reaction <sup>12</sup>C(n, n′) [Q = -9.641 MeV] using a DD-neutron source
1994, Nuclear Inst. and Methods in Physics Research, A
TOF spectra of scattered breakup neutrons from a DD source were simulated in order to separate this fraction from inelastically scattered monoenergetic neutrons. The input data of such simulation had to be examined extensively on the basis of experimentally determined breakup spectra. After subtraction of the simulated breakup spectra from TOF spectra obtained in neutron scattering on carbon, the cross sections related to the third excited state in ¹²C (E_cx = 9.641 MeV) could be extracted. A comparison with results using monoenergetic neutron sources shows a good agreement.
Neutron elastic and inelastic scattering from carbon in the energy range 16.5-22.0 MeV
1989, Nuclear Physics, Section A
The Studsvik high-resolution, low-background time-of-flight facility has been used to obtain a comprehensive set of differential neutron-scattering cross sections for carbon at the neutron energies 16.5, 17.6, 18.7, 19.8, 20.9, 21.6 and 22.0 MeV. Angular distributions in the range 10–160° have been measured for elastic scattering, and also for inelastic scattering from the levels at 4.44, 7.65 and 9.64 MeV. Angle-integrated cross sections have been determined by fitting Legendre polynomial expansions to the differential data.
The results have been treated in terms of a phenomenological spherical optical model. Potential depths and geometrical parameters were determined from fits to the elastic-scattering data, while deformation parameters were obtained from inelastic scattering using the distorted-wave Born approximation.
Elastic and inelastic angular distributions were also calculated with the coupled-channels formal-
Neutron-neutron quasifree scattering in the <sup>2</sup>H(n, nn)p reaction at E<inf>n</inf> = 14.1 MeV
1978, Nuclear Physics, Section A
Neutron-neutron quasifree scattering has been studied in the deuteron break-up reaction ²H(n, nn)p at E_n = 14.1 MeV. Two coplanar and symmetric configurations have been investigated in a kinematically complete experiment where the detection of the spectator particle was not possible. The experimental cross sections are compared with “exact” calculations derived from Faddeev-type equations solved with S- and P-wave nucleon-nucleon separable interactions. These calculations agree both in shape and magnitude with the differential cross section for the θ₁ = − θ₂ = 40° configuration (E_p^min = 0). At θ₁ = − θ₂ = 30° (E_p^min = 180 keV). however, the absolute value of the measured cross section is too high and an observed structure in the shape of the differential cross section is in sharp conflict with the now available “exact” calculations.
EFFI-EIN Monte-Carlo-programm zur berechnung der nachweiseffektivität eines neutronendetektors mit organischem szintillator
1973, Nuclear Instruments and Methods
The Monte-Carlo-program EFFI, described in the present paper, simulates the detection process of neutrons within a cylindrical organic scintillator for incident neutron energies up to 15 MeV. The calculation of detection efficiency for the liquid scintillator NE 213 at the detection threshold of 0.81 MeV shows the important role of the ¹²C(n,α)⁹Be and ¹²(n,n′)3α reactions above 9 MeV neutron energy. The contribution of multiple neutron scattering to the detection efficiency is also multiple neutron scattering to the detection efficiency is also investigated in detail. Approximative calculations in the framework of analytical expressions for the efficiency are compared with EFFI's results to draw conclusions about applicability of these expressions and their limitations.
Neutron scattering from Bismuth, Strontium and Sodium at 14.8 MeV
1972, Nuclear Physics, Section A
Differential cross sections for the elastic and inelastic scattering of 14.8 MeV neutrons from Bi, Sr and Na have been measured with four neutron detectors participating in a time-of-flight system which had an energy resolution of 900 keV for the incident neutrons. The whole procedure was checked by scattering from carbon. For the elastic scattering of Bi, Sr and Na satisfactory optical-model fits were obtained. The absolute cross sections for excitation of collective states are compared to the distorted-wave theory for direct reactions, and a reasonable agreement has been found. The nuclear deformation parameters are extracted and compared to the values from other experiments.
Angular correlations in inelastic neutron scattering by carbon at 15.0 MeV
1971, Nuclear Physics, Section A
The ¹²C(n, n'γ)¹²C reaction has been studied at 15.0 MeV. Absolute neutron-gamma angular correlation data were taken with the γ-detector in the reaction plane and perpendicular to that plane. The neutron spin-flip probabilities are determined. Differential elastic and inelastic neutron scattering cross sections and the differential cross section of the 4.44 MeV deexcitation γ-rays were obtained simultaneously during the angular correlation experiment. The results are compared with other experimental determinations and theoretical predictions. No significant differences between neutron and proton scattering are found.
