Notes:
The distributions of metastable excited state (4F7/2) and ground state (4F9/2) Rh atoms ejected from Ar+-bombarded Rh{100} are experimentally determined as a function of ejection velocity and angle. Corresponding theoretical predictions are made by incorporating a nonradiative deexcitation model into molecular dynamics simulations of the bombardment process. There is good agreement between the experimental and theoretical distributions. The simulations show that a fraction of the ejected atoms are excited via collisions 1–20 A(ring) above the surface, and that these atoms make a significant contribution to the excited atom yield at low ejection velocities.
