In the resonance theory of nuclear reactions with nucleons the collision matrix is divided into two parts: corresponding to the bound and decaying eigen-states respectively. Treating these parts as the matrix of direct interaction and that of compound resonances respectively, the structure of bound-state widths and the complex potential model are discussed.
