Abstract: We study multipoint scatterers with bound states at zero energy in three-dimensional space. We construct examples of such scatterers with multiple zero eigenvalues or with strong multipole localization of zero-energy bound states.

Keywords: Schrödinger equation, multipoint scatterer, bound state, zero energy, localization.
