A dressing of zero-range potentials and electron-molecule scattering problem at low energies
Abstract
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 Xn and YXn structures is studied. The possibilities of dressed ZRP are illustrated by model calculation of the low-energy electron-Silane (SiH4) scattering. The results are discussed. Key words: multiple scattering, silane, zero range potential.
