摘要：

An empirical, composite interatomic potential is developed to describe interaction of energetic particles by pair potentials at high energies and many-body potentials at low energies. Molecular-dynamics studies of low-energy collision cascades are performed. The displacement threshold surface in copper is investigated and compared to experimental data. Our computer simulations show good agreement with the experimental results of King and Benedek at 10 K.
