Investigation of angular correlations in reaction of inelastic scattering of neutron with energy 14.1 MeV on 12C

In this paper, we describe an experimental setup designed to investigate double and triple angular correlations, specifically [Formula: see text] and [Formula: see text]-correlations. The experiment was conducted by the TAgged Neutrons and Gamma-RAys (TANGRA) group at the Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research. A key feature of this experiment is the implementation of the tagged neutron method, which enables the determination of the emission direction and propagation of neutrons tagged with [Formula: see text]-particles ([Formula: see text]) resulting from the [Formula: see text] reaction. The deuterium–tritium reaction releases approximately 80% of its energy through the emission of 14[Formula: see text]MeV neutrons. Neutrons scattered by the irradiated target sample were detected using long plastic scintillation detectors, each equipped with fast photomultipliers at both ends. The dual photomultiplier configuration enhanced the position sensitivity of these detectors and improved their angular resolution.
