    • Sowa et al. used LEED intensity - voltage spectra to determine that interlayer spacing for the first four layers contracts, with the first layer contracting the most and the subsequent layers contracting less with increasing depth. They also determined that platinum atoms in the second and fourth layers move towards the missing row, producing a slightly buckled trough.

    • The classical turning point away from the surface is strictly defined as the point where the z-direction center of mass velocity of the molecule changes sign from positive to negative. The negative direction is into the surface.

    • Helicopter motion is defined as rotation with the angular momentum vector (J) directed along the surface normal (z-direction) while cartwheel motion is defined as rotation with J parallel to the surface (x-y plane).

    • For this discussion it is useful to think of perpendicular energy as indicative of the relative magnitude of α since it indicates the average energy immediately accessible for escape from the surface; for low values of α it may be positive.
