中文摘要：

采用振动密耦合方法,研究了低能电子与H2分子碰撞的振动激发积分散射截面.研究表明,使用18个Morse振动波函数、5个分波和4个对称性可以得到收敛的0→0,0→1,0→2和0→3积分散射截面;而且振动波函数的性质和振动能级的精确性会直接影响振动激发散射势能和振动激发积分散射截面.计算结果与实验符合得很好.

英文摘要：

The vibrational excitation integrated cross sections（ICSs）of the low-energy electron-H_2 scattering are studied using the vibrational close-coupling（VCC）method.18 Morse vibrational states,5 partial waves and 4 molecular symmetries are used to converge the vibrational excitation ICSs.It is shown that the properties of the vibrational excitation scattering potentials and the accuracy of the vibrational excitation ICSs may be affected by the quality of the vibrational wavefunctions and the accuracy of the vibrational energies. The converged vibrational excitation （ v0 = 0→ v = 0,1,2,3） ICSs agree well with the known experimental results.
