Multicrystal Scintillation Detector for Investigation of Angular Correlations in $({\rm n},\gamma )$ Reactions

An improved method for the study of time reversal (T) violation is described. It consists of measurement of the forward-backward asymmetry in direct γ-ray transitions after unpolarized neutron capture in p-wave resonances. The γ-ray detection system with 12 BGO crystals and the DAQ system based on flash ADC modules were tested.
