Abstract
An F-atom with ∼1 eV translational energy was aimed at a line of fluorocarbon adsorbates on Cu(110). Sequential 'knock-on' of F-atom products was observed by STM to propagate along the 1D fluorocarbon line. Hot F-atoms travelling along the line in six successive '' cycles paralleled the rocking of a macroscopic Newton's cradle.
摘要
一个具有约1电子伏特平动能量的氟原子被对准铜（110）表面上的一排碳氟吸附质。通过扫描隧道显微镜（STM）观察到氟原子产物的连续“撞击”沿着一维碳氟链传播。热的氟原子在六个连续的“循环”中沿着该链移动，这类似于宏观牛顿摆的摆动。
