【摘要】 用T.T(Tang-Toennies)势模型和密耦计算方法分别计算了入射原子的相对碰撞能量E=0.05eV,0.15eV,0.25eV时He,Ne,Ar,Kr,Xe-D2碰撞体系的00-00弹性碰撞和00-02非弹性碰撞分波截面,得到了惰性气体原子与D2分子碰撞分波截面随量子数增加和体系相对碰撞能量增加的变化规律.结果表明:对00-00弹性碰撞,分波截面随量子数J的增加不断振荡,并出现一些尾部效应;而随入射原子的相对碰撞能量的变化,振荡极大值位置、收敛分波数均不断变化.更多还原

【Abstract】 By using close-coupling equation and Tang-Toennies potential for the He,Ne,Ar,Kr,Xe-D₂ system,the partial wave cross sections of 00-00 elastic collision and 00-02 unelastic collision at collision energy E=0.05,0.15 and 0.25eV were calculated,and the changing regularities of them for inertia atom and D₂ collision with the increase of quantum number and the relative kinetic energy of incoming atoms were obtained from this calculation,result: the partial wave cross sections of the 00-00 elastic collision fluctuate continuously as J increasing,and tail effect appears,the situation where fluctuation maxium occurs and convergent partial wave number all changing continuously with the relative kinetic energy increasing of incoming atoms.更多还原
