Nature of problem:Subroutine DEUT is a Fortran IV subroutine designed to calculate the binding energy and wavefunction of the neutron-proton J=1+ bound 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. This subroutine may also be employed in nuclear Hartree-Fock calculations using an effective nucleon-nucleon potential containing a tensor component, and in all those eigenvalue problems reducible to that of a particle moving under the influence of a force containing a tensor component. | ||

Solution method:The requirements that the wavefunctions vanish at the origin and at infinity cause this to be an eigenvalue problem: the technique used for the solution involves a direct numerical integration of the differential equations with middle point matching, accompanied by the iterative application of a suitable correction formula for a trial value of the binding energy. | ||

Restrictions:The interparticle potentials considered in the program are the Hamada- Johnston potential and the Reid hard-core or soft-core potentials. To use subroutine DEUT in the case of some other potential one must simply re-write the subprogram POT. | ||

Running time:The test case requires 85 seconds to compile and 15 seconds to run on the IBM 7090 computer at Pisa University. | ||
