摘要

First principles calculations show that two-body forces are sufficient to describe interactions of He with fcc Cu and bcc Nb. This property is explained directly from calculated charge density distributions and used to construct a Cu-Nb-He interatomic potential that predicts accurate He impurity energies despite not being fitted to them.
