Popis:	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 Ep = 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.
