摘　　要：用BFW势模型和密耦近似方法,计算了入射He原子能量分别为75,100和200meV时与基态HBr分子碰撞的弹性和非弹性分波截面,得到了态-态分波截面随量子数增加的变化规律.The Barker potential-type（BFW） model and close-coupling approximate method are utilized to calculate the elastic and inelastic partial cross sections for He atom collision with HBr molecule of the ground state.The calculation is performed at the incident energies of 75,100 and 200meV,respectively.The law of changing of the state-to-state partial cross sections with the increase of quantum number has been obtained.
