We study bound states of a three-particle system in R3?> described by the Hamiltonian H(λn) = H0 + v12 + λn(v13 + v23), where the particle pair {1, 2} has a zero-energy resonance and no bound states, while other particle pairs have neither bound states nor zero-energy resonances. It is assumed that for a converging sequence of coupling constants λn → λcr the Hamiltonian H(λn) has a sequence of levels with negative energies En and wavefunctions ψn, where the sequence ψn totally spreads in the…
