Abstract
We present an R -matrix Fortran package to solve coupled-channel problems in nuclear physics. The basis functions are chosen as Lagrange functions, which permits simple calculations of the matrix elements. The main input is the coupling potentials at some nucleus–nucleus distances, specified by the program. 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.
