Description

An extension to the Monte Carlo assisted Classical Method (MCCM) methodology was developed and implemented. The extension allows to calculate the atom displacement per atom (dpa) profiles considering threshold displacement energies which are spatially inhomogeneous. Calculation of the dpa profiles was performed using both, the standard methodology and extended one for gammas of 1.25, 3, 7 and 12 MeV energies for the BaTiO${}_3$ ceramic. Significant differences for the oxygen sublattice in all the energy range were found, being these ones the highest ones. In general, the dpa profiles calculated at the same sample deep and energy with the standard MCCM are between one or two orders higher than the ones calculated through the extension.
