低能电子与H₂分子高振动激发散射动量迁移截面的研究

摘要: 采用体心坐标系下振动密耦合方法研究低能电子与H₂分子高振动激发散射的动量迁移截面(momentum transfer cross section, MTCS)。通过对包含18个振动态、8个分波和16个分子对称性的研究, 得到了收敛的密耦合框架下的v=0→v′=5, 6, 7, 8, 9, 10等几个振动跃迁通道的动量迁移截面值, 为进一步精确研究低能电子与H₂分子的相互作用机理奠定了基础。

Abstract: Body frame vibrational close-coupling method is used to study highly vibrational scattering of low energy electron hydrogen molecule.The converged momentum cross sections(v=0→v′=5, 6, 7, 8, 9, 10)are obtained by using 18 vibrational states, 8 partial waves and 16 molecule symmetry.These data are very useful for studying the exact interaction between the incident electron and hydrogen molecule in future research.
