Molecular dynamics simulation of low-energy atomic displacement cascades in a simplified nuclear glass

In a simplified (SiO2, B2O3, Na2O3, Al2O3, ZrO2) nuclear glass the authors simulated secondary cascades resulting from the first atoms displaced by a collision with a recoil nucleus. Although the acceleration energies applied to the primary atom were relatively low, the study yielded a number of interesting results, notably concerning a tendency toward diminishing network connectivity, the nature of the atoms most frequently displaced and the mechanisms involved.
