低能下的多重散射和电子-尿嘧啶碰撞
Multiple scattering and electron-uracil collisions at low energies
摘要：
两个众所周知的方法之间的联系：零范围和非重叠（松饼罐）的潜力的方法进行了讨论。讨论了零程电位法的一些难点及其消除方法。我们认为，这种先进的ZRP势方法可以应用于现实的电子分子过程。该方法将电子-分子散射问题转化为厄米矩阵的广义本征值问题，并具有快速数值格式。该方法的一个显著特点是可以直接计算波函数（分波）。该理论被应用到电子尿嘧啶散射。在低能量的部分阶段和横截面进行评估和绘图。
英文摘要：
Links between two well known methods: methods of zero-range and non-overlapped (muffin-tin) potentials are discussed. Some difficulties of the method of zero-range potentials and its possible elimination are discussed. We argue that such advanced method of ZRP potential can be applied to realistic electron-molecular processes. The method reduces electron-molecule scattering to generalized eigenvalue problem for hermitian matrices and admit fast numerical scheme. A noteworthy feature of the method is direct possibility to calculate the wave functions (partial waves). The theory is applied to electron-uracil scattering. Partial phases and cross-sections at low energies are evaluated and plotted.
