Abstract
The orthogonal projection technique proposed previously by the authors is used to construct an effective formalism aimed at calculations and study of two- and many-body resonances. The iterative formalism developed permits converging series for the energy, width and wavefunction of a many-body resonance to be constructed. Explicit expressions for the contributions of individual channels to the energy shift and decay width are given. In particular, for three-body resonance decay it is shown that the contributions from three- and two-body decays can be discriminated explicitly and do not interfere. Illustrative examples demonstrating the effectiveness of the formalism developed are presented.
