Abstract
High precision benchmark calculations for phase shifts and mixing parameter s as well as observables in elastic neutron-deuteron scattering below the d euteron breakup threshold are presented using a realistic nucleon-nucleon p otential. Two totally different methods, one using a variational principle in configuration space and the other solving the Faddeev equations in momen tum space, are used and compared to each other. The agreement achieved in p hase shifts and mixing parameters as well as in the polarization observable s is excellent. The extreme sensitivity of the vector analyzing power A(gam ma) to small changes of the phase shifts and mixing parameters is pointed o ut. [S0556-2813(98)07312-9].
