“…Usually, the angular distributions of the discrete γ -rays produced in the inelastic scattering of neutrons are expressed by the first three even terms of the Legendre polynomials expansion. In the past this reaction was widely investigated, but controversial results on the anisotropy of the γ -rays from the 12 C(n,n γ ) 12 C-reaction were obtained by different groups of scientists [7][8][9][10][11][12][13][14][15][16][17][18][19][20], particularly, at small n'-scattering angles (Fig. 5).…”

Abstract. For investigation of the basic characteristics of 14.1 MeV neutron induced nuclear reactions on a number of important isotopes for nuclear science and engineering, a new experimental setup TANGRA has been constructed at the Frank Laboratory of Neutron Physics of the Joint Institute for Nuclear Research in Dubna. For testing its performance, the angular distribution of γ -rays (and neutrons) from the inelastic scattering of 14.1 MeV neutrons on high-purity carbon was measured and the angular anisotropy of γ -rays from the reaction 12 C(n, n γ ) 12 C was determined. This reaction is important from fundamental (differential cross-sections) and practical (non-destructive elemental analysis of materials containing carbon) point of view. The preliminary results for the anisotropy of the γ -ray emission from the inelastic scattering of 14.1-MeV neutrons on carbon are compared with already published literature data. A detailed data analysis for determining the correlations between inelastic scattered neutron and γ -ray emission will be published elsewhere.

“…The limiting angular resolution is determined by chromatic and geometric ion-optic aberrations, effects of alphaparticle scattering in the tritium target and neutron scattering in the target holder; and in case of ING-27 it is close to 2 − 3• [5].…”

“…It was used for measuring angle correlations of products of inelastic scattering of fast neutrons in numerous works, e.g. [5,7]. Currently, a cycle of experiments for study (n, n′γ) and (n, 2n′) reactions is run at TANGRA setup [8] (Figure 4 Based on gamma-ray energy and emission location obtained as the result of the acquired data processing, a 3D map of chemical composition of the interrogated object can be generated.…”

Abstract. Each 14 MeV neutron of T(d,n)He4 reaction is accompanied (tagged) by 3.5 MeV alpha-particle emitted in the opposite direction. A position-and time-sensitive alpha-detector measures time and coordinates of the associated alpha-particle for determining the time and direction of the neutron escape. A spectrum of gamma rays emitted as a result of the interaction of tagged neutrons with nuclei allows the identification of the chemical composition of the irradiated object. The recording of alpha-gamma coincidences within a very narrow time window provides the possibility of background suppression by means of spatial and time discrimination of events. The Nanosecond Tagged Neutron Technology (NTNT) based on this principle has great potentialities in various fields, such as the study of neutron scattering, revision of neutron differential cross-sections, measuring the chemical composition of ores in mining industry, the detection of explosives, mines, drugs and chemical warfare agents, etc. The Dukhov Research Institute of Automatics produces a complete set of NTNT equipment, including neutron generators with built-in alpha-detectors, electronic hardware for alpha-gamma coincidence data acquisition, mobile and stationary NTNT systems for various research, industrial and homeland security applications.
