Abstract

We employ a Birman-Schwinger type analysis to derive estimates on the number of bound-states of certainN-body systems with threshold-energy ∑=inf δess(H) supposed to be zero. For many-body systems without any substructure we show that eigenvalues of the Schrödinger operatorH absorbed at Σ=0 are in the point-spectrum ofH. Furthermore we characterize a multiparticle equivalent of the Efimov effect.
