An R -matrix package for coupled-channel problems in nuclear physics

The program provides the collision matrix and, optionally, the associated wave function. The present method deals with open and closed channels simultaneously, without numerical instabilit... Title of program: rmatrix Catalogue Id: AEYP_v1_0 Nature of problem Solving coupled-channel problems for positive energies; the package provides the collision matrix and the associated wave function for given energy, spin and parity.
