Description
A study of the inelastic scattering of neutrons with an energy of 14.1 MeV on the light nuclei was carried out at the TANGRA facility at JINR (Dubna) using the tagged neutron method (TNM) [1]. The D-T neutron generator ING-27 with built-in position sensitive detector of $\alpha$-particles was employed as a source of tagged 14.1 MeV neutrons. Different types of detector systems were used to register gamma quanta and scattered neutrons from reactions induced by the neutrons hitting the target used. The $\gamma$-rays were measured by means of two high-purity germanium (HPGe) detectors and four LaBr$_3$ scintillators positioned at specific angles [2]. The most complete data were obtained with a carbon target, for which the scattered neutrons and $\gamma$-rays were measured by an array of plastic scintillator detectors surrounding the graphite target. The neutron/gamma separation and determination of scattered neutron energies were done by the time-of-flight method.
New results on differential cross sections of $\gamma$-ray emission, as well as neutron-gamma angular correlations will be presented.
