Abstract: A molecular dynamics simulation has been used to study zero-fluence and low-bombarding-energy 63Cu-65Cu sputtering. Calculations show that the isotopic ratios at both θ≤35° and θ>35°, and the total isotopic ratio increase when the bombarding energy decreases. This result might imply the existence of the bombarding-energy-dependent momentum asymmetry.
