520.3.#.a: In the present paper a descrption of a many channel nuclear reaction is given on the basis of the formalism of boundary conditions introduced some years ago by moshinsky. It is supposed that the interaction between the particles takes place at the point of contact. As a result of the interaction, they can form a compound particle, which is the analogous of the compound nucleus in a nuclear reaction. The behavior of the wave function describing the relative motion of the particles in the different channels, is determined by a set of conditions they must satisfy at the point of contact. In this formalism we have also the possibility of a direct interaction, i.e., reactions which proceed without the formation of a compound particle. we derive the general form of the s-matrix, which includes both the compound nucleus and the direct interaction contributions. We give an interpretation of the modulation of the reduced widths of the resonances associated with the compound particles, modulation that was explained by the optical nuclear model. Finally, we discuss the behavior of the transfer cross section when the reaction takes place through the direct interaction mechanism.

Resumen
In the present paper a descrption of a many channel nuclear reaction is given on the basis of the formalism of boundary conditions introduced some years ago by moshinsky. It is supposed that the interaction between the particles takes place at the point of contact. As a result of the interaction, they can form a compound particle, which is the analogous of the compound nucleus in a nuclear reaction. The behavior of the wave function describing the relative motion of the particles in the different channels, is determined by a set of conditions they must satisfy at the point of contact. In this formalism we have also the possibility of a direct interaction, i.e., reactions which proceed without the formation of a compound particle. we derive the general form of the s-matrix, which includes both the compound nucleus and the direct interaction contributions. We give an interpretation of the modulation of the reduced widths of the resonances associated with the compound particles, modulation that was explained by the optical nuclear model. Finally, we discuss the behavior of the transfer cross section when the reaction takes place through the direct interaction mechanism.
