The original formulations of the theory came from nuclear scientists Wigner[2][3], Eisenbud, Breit[4], Blatt, Weisskopf, and others.
[6] The term R-matrix is used in connection with the Yang–Baxter equation, first introduced in the field of statistical mechanics in the works of J.
The numerical modeling of diffraction gratings in optical science can be performed using the R-matrix propagation algorithm.
[11] There is a method in computational quantum mechanics for studying scattering known as the R-matrix.
Using the original R-matrix theory as a basis, a method was developed for electron, positron and photon scattering by atoms.
