Abstrakt: Nondestructive structural methods of neutron diffraction and neutron tomography have been used to study he phase composition and spatial distribution of chemical components in the bulk of a bronze zoomorphic bear-shaped pommel. The pommel, which belongs to the Ananyino cultural and historical region dated 1st millennium BCE, was found close to the Pekunovsky settlement near Dubna, Moscow oblast. Studies have shown that the zoomorphic ornamentation, which was made of tin bronze, contains two main crystalline phases: bronze and cuprite Cu2O. The reconstructed neutron tomographic data revealed the uneven distribution of phase components within the bulk of the pommel, which may be indicative of the deep bulk penetration of corrosion products, copper cuprite. The volumetric contents of bronze and corrosion have been obtained, and the concentration of tin in the bronze alloy has been calculated. [ABSTRACT FROM AUTHOR]
