Calculation of the atom displacement concentration in YVO₄ and PbMoO₄ crystals as a function of electrons or neutrons energy

Abstract

This work is devoted to the calculation of concentration of radiation displacement defects (RDDs, i.e. atoms, cations or anions displaced from positions in lattice and their associated vacancies) in YVO₄ and PbMoO₄ crystals as a function of particle energy (electrons and neutrons). Energy dependencies of RDD concentrations are discussed in comparison with results of other complex oxide crystals. The obtained results show that the case of electron irradiation the radiation hardness of YVO₄ and PbMoO₄ is higher than for other oxide crystals.

Keywords:

• electron and neutron irradiation
• radiation displacement defects
• oxide crystals
