“…3) the data seems to be compatible with all theoretical predicitons with exception of data from Ref. [15]. That data set taken in the region of energies 12 MeV < E n < 22 MeV clearly advocates the CD Bonn potential predicitons However, it does not exclude definitly values of cross sections obtained with λ = 1.21.…”

We investigate how strong a hypothetical 1 S 0 bound state of two neutrons would affect different observables in the neutron-deuteron reactions. To that aim we extend our momentum space scheme of solving threenucleon Faddeev equations to incorporate in addition to the deuteron also the 1 S 0 dineutron bound state.We discuss effects induced by dineutron on the angular distribution of the neutron-deuteron elastic scattering and cross sections of the deuteron breakup. A comparison to the available data for neutron-deuteron total cross sections and elastic scattering angular distributions cannot decisively exclude a possibility that the two neutrons can form 1 S 0 bound state. However, the strong modifications of a final-state-interaction peak of the neutron-deuteron breakup when changing from negative to positive values of the neutron-neutron scattering length seems to exclude existence of dineutron.

“…All of the detectors (NE230, NE213 reference and NE213 monitor) used in the experiments were equipped with Link Systems Model 5010 pulse discriminator units to suppress the detection of gamma rays. Both the NE230 and NE213 scintillators have excellent capabilities for discriminating against gamma rays as well as between protons, deuterons and alphas by means of pulse shape discrimination [3,7,8]. The output parameters, pulse height L, fast signal F and neutron time-of-flight T from the Link units were recorded in list mode and then processed off-line.…”

A recoil neutron spectrometer based on NE230 deuterated liquid scintillator (25 mm diameter × 25 mm) has been used to investigate neutron energy spectra of scattered neutrons at positions in and near to the beam axis in a water phantom irradiated by a quasi-monoenergetic 64 MeV neutron beam. An important feature of the spectrometer is that it is able to discriminate against backgrounds that can arise from n-p scattering in the water. Neutron energy spectra are obtained from measurements of pulse height spectra by the NE230 spectrometer using the Bayesian unfolding code MAXED. The experimentally measured energy spectra are compared with spectra calculated by Monte Carlo simulation using the code MCNPX.

“…Above 15 MeV, Seagrave et al [5] and Schwarz et al [6] deduced respectively three and seven data points by subtracting the elastic cross section to the total one (empty squares) with large uncertainties between 18% and 30%. Only Pauletta and Brooks [7] directly measured the break-up reaction and published six data points -20% higher than those of Seagrave et al and Schwarz et al -between 16 and 22 MeV with uncertainties of 7-9% (full squares).…”

Abstract. This article presents a running experimental program to measure the neutron-induced deuteron break-up reaction between 5 and 10 MeV, and between 20 and 30 MeV. The measurements are performed with a C 6 D 6 detector as deuteron target placed in a beam line of the Tandem 7MV accelerator at Bruyères-le-Châtel, France, dedicated to the use of a 4π neutron detector which allows to measure the two emitted neutrons. This experimental work is done in parallel with an ab initio calculation of the reaction which is sum up in the text. Comparisons to the measured cross section are done together with CENDL2 and ENDF/B-VII evaluations.
