Solution of the two-nucleons Schrödinger equation with nonlocal tensor potential in the 3S1-3D1 state
Description
Abstract The program NPSD calculates the scattering parameters and deuteron properties for a neutron-proton system in the ^3 S_1 -^3 D_1state when the potential model consists of a local part having cnetral, spin-orbit and tensor components, plus a nonlocal separable tensor contribution of the form γg(r)g(r′)S_(12). The numerical method for solving the radial Schrödinger equation (which in this case, is a pair of coupled integro-differential equations) is given. NPSD can be used with γ = 0 for any... Title of program: NPSD Catalogue Id: ABJH_v1_0 Nature of problem The subroutine NSPD calculates the 3S1-3D1 state properties when the potential model between the two nucleons consists of a local part having central, spin-orbit and tensor components, plus a nonlocal separable tensor contribution of the form lambda S12g(r)g(r'), where S12 is the usual tensor operator. NSPD may be used for nuclear calculations involving realistic nucleon-nucleon potential with a nonlocal tensor part.
