低能电子与氮分子碰撞振动激发动量迁移截面的研究
Studies on the momentum transfer cross sections for low-energy electron scattering by nitrogen molecule
【摘要】 采用作者改进的振动密耦合方法和基于量子力学从头计算的静电势、交换势、相关极化势,研究了低能电子与N2振动激发散射动量迁移截面.计算结果与试验符合较好.
【Abstract】 In this paper,momentum transfer cross sections are obtained using body frame vibrational close-couple method (BFVCC) modified by the authors. Using the static potential,correlation-polarization potential and exchange potential calculated ab-initio,the results accord with experiment very well.
