For investigation of 14.1-MeV neutron-induced nuclear reactions, at Frank Laboratory of
Neutron Physics (FLNP) of the Joint Institute for Nuclear Research (JINR), a project TANGRA
(Tagged Neutrons & Gamma Rays) was created [1].
In the framework of this project, we are investigating the energy and angular distributions of
the characteristic gamma-rays raising from the inelastic scattering (INS) of 14.1-MeV neutrons on a
number of nuclei, using tagged-neutron method (TNM). As a source of tagged neutrons, we are
using a portable neutron generator ING-27 of VNIIA (Moscow), in which 14.1-MeV neutrons are
generated in T(d,n) 4 He fusion reaction. The tagging of the neutrons is done by registering the alpha-particles with a multipixel charge-particle detector. The gamma-rays from the INS-reactions are registering in coincidence with the signals from the alpha-detector, by 18 BGO-detector array “Romasha”, significantly reducing this way the influence of the background scattered radiation.
In this article we are reporting the results obtained in the measurements of the gamma-ray angular distributions from the INS of 14.1-MeV neutrons on 23 Na and 35 Cl nuclei, in comparison with the data of other authors [2].
