本文用量子力学方法处理氢原子的运动，用分子动力学方法计算了吸附在Si（111）表面上的氢原子第一激发伸缩振动的能量弛豫率。弛豫是通过三个弯曲模的激发和188 cm−1声子的发射而发生的。
The energy relaxation rate for the first excited stretching vibration of hydrogen atoms adsorbed on an Si(111) surface is calculated treating the motions of the H atoms quantum mechanically and computing the substrate phonon spectrum by molecular dynamics. The relaxation occurs through excitation of three bending modes and emission of a 188 cm−1 phonon.
