摘要：

The effects of different Fe-He interatomic potentials on primary damage formation in Fe-1%He are investigated using molecular dynamics (MD) methods. Simulations of cascades produced by primary knock-on atoms (PKA) of energy E-p = 0.5-10 keV were performed at an irradiation temperature of 100 K. It is found that the Fe-He potentials have significant effects on the point defect creation and the formation of Fe-He interstitial clusters, whereas small effects on the formation of He-vacancy clusters.
