摘    要:用非绝热近似含时薛定格方程对O2在Ag(110)表面上的吸附进行了计算。计算结果表明:较低温度时,主要呈现氧的分子态吸附,氧处于电荷转移状态O2^-;较高温度时,主要呈现氧的原子态吸附,吸附过程可能经历电荷转移状态O2^-;氧分子的振动激发,有利于分子态吸附,但对原子态吸附无影响。

关 键 词:非绝热近似    吸附    表面吸附  动态学

Abstract:he oxygen adsorption on Ag (110) surface has been studied by calculation with time-dependent Schroedinger equation under non-adiabatic approximation. The calctlation results show that the adsorption is mainly presented as molecular state adsorption at lower temperature, oxygen is at a charge-tranfered state O2-: whereas is mainly atomic state adsorption at higher temperature, the adsorption route may he through a charge transfered state O2-; the vibration excitation of oxygen is favorite for molecular state adsorption but has no influence for atomic state adsorption.
Keywords:on-adiabatic approxition  oxygen adsorption  silver
