Abstract
The transition operator corresponding to a separable nonlocal and of a matrix-type potential is studied theoretically. It is shown that the transition operator possesses the same (or ) dependence and properties of separability and nonlocality as the potential and that it is also of a matrix type. This transition operator is then explicitly calculated. A numerical application is made to the simple but physically important case of the low-energy pion-nucleon interaction. The behavior of the transition operator coefficients versus the incident energy are discussed in detail for , , and waves.
