Abstract

Coupled-channel and dispersive-optical model analyses of published neutron scattering and reaction data for ²⁷Al, ⁵⁹Co, and ⁹³Nb at incident energies between 0.1 and 80 MeV have been performed. The resulting potentials are used to place constraints on the determination of the spin-spin interaction from published spin-spin cross-section measurements. For the three nuclei, the strength of the central real spin-spin potential, which was taken to have a surface plus volume shape, was found to be small. Volume integrals for this central potential component were determined to be in the 4-7 MeV fm³ range and to decrease somewhat as mass number increases.
