摘要:
Deviations of focusons by repulsive and attractive forces at idealized surfaces have recently been proposed to account for ejection other than that exactly along close‐packed directions. The theory is here applied to actual faceted surfaces which are produced by ion bombardment. This treatment brings the deviation theory into very good agreement with experimental results. An earlier theory based on surface twinning to explain ejections parallel to some non‐close‐packed directions in the parent crystal is shown to be untenable.
