Detector array for 7H nucleus multi-neutron decay study

Publications, 15 March 2023

We offer to your attention a preprint “Detector array for the 7H nucleus multi-neutron decay study” E13-2022-56 published by the JINR Publishing Department. The authors are Bezbakh A. A. et al.

A setup fitting the requirements for the detailed study of the five-body decay of the 7H nucleus obtained as a result of the proton transfer from the 8He projectiles to the deuterium target nuclei is being built at the radioactive beam line of the ACCULINNA-2 separator at the Flerov Laboratory of Nuclear Reactions. Described here are the assembly of 100 BC-404 plastic scintillators, intended for neutron detection, the annular Si detector telescope for the 3He recoils, and the detector array providing the Δ E–E–ToF registration of 3H nuclei emitted at the 7H 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 experiments discussed.

The study has been carried out at the Flerov Laboratory of Nuclear Reactions.
