  • 严格交换势用于研究低能电子与H2分子的弹性和非弹性散射截面,线性代数方法和R-矩阵传播子相结合求解基于振动密耦合方法的积分-微分耦合方程组,由此得到收敛的(0→0,0→1,0→2)散射微分截面和积分截面.理论计算结果与目前优秀的实验值和其他理论计算值进行了比较,表明基于振动密耦合方程的严格交换势在低能电子与H2分子振动激发散射中有重要作用.
    Elastic and inelastic differential and integral cross sections for low-energy vibrational excitation of H2 by electron impact are studied with exact exchange. The resulting coupled integrodifferential equations are solved using a combination of linear-algebraic and R-matrix-propagator techniques. The converged (0→0,0→1,0→2) differential and integral cross sections are obtained. The calculated results are in good agreement with experimental resalts and other calculations, showing that the exact exchange based on equations of vibrational close coupling plays an important role in low-energy electron scattering from H2 molecule.

摘要: 严格交换势用于研究低能电子与H2分子的弹性和非弹性散射截面,线性代数方法和R-矩阵传播子相结合求解基于振动密耦合方法的积分-微分耦合方程组,由此得到收敛的(0→0,0→1,0→2)散射微分截面和积分截面.理论计算结果与目前优秀的实验值和其他理论计算值进行了比较,表明基于振动密耦合方程的严格交换势在低能电子与H2分子振动激发散射中有重要作用.
