摘要：

We report on the spin-dependent neutron scattering length on He-3 from a microscopic calculation of p-H-3, n-He-3, and d-H-2 scattering employing the Argonne v(18) nucleon-nucleon potential with and without additional three-nucleon force. The results of a comprehensive R-matrix analysis are compared to that of a recent measurement. The overall agreement for the scattering lengths is quite good. The imaginary parts of the scattering lengths are very sensitive to the inclusion of three-nucleon forces, whereas the real parts are almost insensitive.
