Three dimensional He scattering on a model surface

He atom beam is scattering on an irragularly stepped model surface. A "window" parallel to the surface has been chosen near the surface (~4 a.u.) at the interaction region. The probability density function of He atom is rendered as the time progresses in the above mentioned "window". Atomic units (a.u.) are used.
