Determining the Elemental Composition of Antique Coins of Phanagorian Treasure by Neutron Spectroscopy at the Pulsed Neutron Source IREN in FLNP JINR

Abstract—Neutron Resonance Capture Analysis (NRCA) is currently being developed in the Frank Laboratory of Neutron Physics (FLNP) for the purpose of determining the element composition of samples. This method is based on registering neutron resonances in radiative capture and measuring the yield of reaction products in these resonances. To test the capabilities of this method, such investigations have been carried out in collaboration with the Institute of Archaeology of the Russian Academy of Sciences at the IREN pulsed neutron source, FLNP, for ancient coins from Phanagorian treasure. A cylindrical multisectional liquid scintillator detector is used to detect γ-quanta.
