Two years ago, in a lecture given at the Schladming Conference 1972, I reviewed the present status of the quantum mechanical three-body problem [1]. It was the main intention of this survey to illustrate the way in which the properties of the integral equations, studied in this field, are related to basic concepts of multichannel collision theory. Such a consideration makes the typical difficulties of older attempts rather transparent. Moreover, the modern approaches initiated by Faddeev’s work [2], are easily understood as natural consequences of general features of the multichannel theory.

    Without going into any details we recall that in the Heisenberg picture the relevant operators have to be sandwiched between eigenstates of the total Hamiltonian. These, however, are in our case the scattering statesGoogle Scholar

    A detailed investigation, sketched in Ref. 1, shows that the uniqueness of the Faddeev equations is a consequence of the fact that their algebraic structure corresponds exactly to decisive aspects of the multichannel collision theory. The original, more technical proof of uniqueness [2] was based on methods of integral equations theory. From both points of view it is important that the expression (3.8) represents an exchange potential, different from zero only for a 6, or, in other words, that the kernel of the system of equations (3.4) has no diagonal elements.Google Scholar
