Detector Array for the 7H Nucleus Multi-Neutron Decay Study

Abstract

Setup fitting the requirements for the detailed study of the five-body decay of the 7 H nucleus obtained as a result of the proton transfer from the 8 He projectiles to the deuterium target nuclei is being built at the radioactive beam line of ACCULINNA-2 separator in the G.N. Flerov Laboratory of Nuclear Reactions. Described here is the assembly of 100 BC-404 plastic scintillators, intended for neutron detection, the annular Si detector telescope for the 3 He recoils, and the detector array providing the ΔE–E-TOF registration of 3 H nuclei emitted at the 7 H decay. Results obtained by the Monte Carlo simulations made for the energy values and flight passes of all these particles are given together with the luminosity expected for the discussed experiments.
