Energy spectrum of a particle in potentials with strongly differing ranges
Description
This paper presents equations that are derived to determine the spectrum of weakly bound states of systems in which the interaction is described by a superposition of potentials with strongly differing interaction ranges. The level shifts in a long-range potential due to the influence of a shortrange center are found. The interaction of levels that exist in the isolated potentials is investigated. Expressions for the renormalization of the scattering length by an external field are obtained, and the Stark effect under conditions of degeneracy is considered
