Abstract.

 The hyperspherical adiabatic representation is reviewed. Both the advantages and disadvantages of this representation are discussed. Zero-range potentials are introduced as one way to circumvent one of the disadvantages. It is shown that such potentials can be used to model complex multiparticle interactions. An application to magnetic tuning of Feshbach resonances shows how complex processes can be modeled in a fairly simple way.
