Electronic Excitation of Rh atoms above the Surface
Gif picture       Experimental energy and angular distributions of neutral Rh atoms sputtered in the excited 4F7/2 state vs. the ground 4F9/2 state indicate anomolous excitations probabilities for the low energy excited 4F7/2 Rh atoms. Simulations clearly show that collisions of atoms above the surface are responsible for the anomolous excitation probability. The original animation was made by Dan N. Bernardo. The color coding for the atoms is shown to the left. See the references given below for further details.
