Farm — A flexible asymptotic R-matrix package

Abstract
The R-matrix formalism has been highly successful in describing a wide range of atomic and molecular scattering problems. A computational bottleneck in these calculations is the treatment of the scattering in the external region of configuration space where exchange effects may be neglected. A new package for solving this external region scattering problem is described. The package uses a combination of R-matrix propagation techniques to ensure optimum stability and efficiency in integrating ...

Title of program: FARM
Catalogue Id: ADAZ_v1_0

Nature of problem
The program solves the scattering problem in the asymptotic region of R-matrix theory where exchange is negligible.
