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