零程势的修正与低能电子-分子散射问题

A dressing of zero-range potentials and electron-molecule scattering problem at low energies

S. B. Leble, S. Yalunin

摘要:

考虑了一个非球形势的修饰,其中包括$n$零程势。采用修整技术对ZRP模型进行了改进。为了进行达布变换,我们引入了非球势的分波和分相的概念。研究了规则$\hbox{X}_n$和$\hbox{YX}_n$结构上的散射问题。通过低能电子-硅烷($\hbox{SiH}_4$)散射的模型计算,说明了修饰ZRP的可能性。并对结果进行了讨论。关键词:多重散射,硅烷,零程势。

英文摘要:

A dressing of a nonspherical potential, which includes $n$ zero range potentials, is considered. The dressing technique is used to improve ZRP model. Concepts of the partial waves and partial phases for non-spherical potential are used in order to perform Darboux transformation. The problem of scattering on the regular $\hbox{X}_n$ and $\hbox{YX}_n$ structures is studied. The possibilities of dressed ZRP are illustrated by model calculation of the low-energy electron-Silane ($\hbox{SiH}_4$) scattering. The results are discussed. Key words: multiple scattering, silane, zero range potential.
