The two-nucleon effective-range parameters with tensor forces

Title of program: EFFECTIVE RANGE APPROXIMATION Catalogue Id: ABGJ_v1_0 Nature of problem Subroutine EFRNG is a Fortran IV subroutine designed to calculate the zero energy wavefunction of the neutron-proton J=1+ state when the interaction between the particles is described by a given combination of central, tensor and spin-orbit potentials with or without a hard- core. From this one derives the effective range parameters, viz. The scattering length and effective range in terms of which can be expressed the low energy scattering behaviour. This subroutine may also be employed in the r ...
