Abstract. Exact formulae of the semirelativistic approximation (up to the square of momentum) to the Dirac-Pauli eqution are deduced. Using the potentials of the Laplacean force (exponentially decreasing Newtonian force), the theory is applied to the np-scattering over the energy interval from 10 to 40 MeV. The calculated elastic scattering cross-sections coincide with the experiments in the limits of the experimental error.
