© 2022 Elsevier B.V.This article demonstrates the performance of the EJ-276 plastic scintillator-based neutron radiation spectrometer with neutron–gamma separation capability. This work continues the earlier research devoted to the demonstration of the EJ-276 spectrometric capabilities. An NG-150M generator located at RFNC-VNIIEF (Sarov) was used as a neutron source. Neutron energy distribution was unfolded for several angles between neutron generator and the target-scintillator direction using a Geant4 simulated response matrix and a set of experimental response spectra. The experimental neutron spectra are compared with the calculated ones. DT neutron unfolded energy uncertainty is 2%. The accompanying gamma radiation spectra were unfolded with the same uncertainty.
