POINT INTERACTIONS IN THE PROBLEM OF 3 QUANTUM PARTICLES WITH INTERNAL STRUCTURE

A system of three quantum particles with internal structure in which t he two-body interactions are point interactions and are described in t erms of two-channel Hamiltonians is considered. It is established that in the cases when the parameters of the model are such that the total Hamiltonian of the three-particle system is semibounded the Faddeev e quations are Fredholm equations. Boundary conditions are formulated fo r the differential Faddeev equations whose solutions are the scatterin g wave functions.
