Abstract
It is shown that the strongest (similar to r(-3)) singularities at sma ll interparticle distances, arising from the spin-tenser forces in the standard nonrelativistic one-boson-exchange (OBE) potentials, disappe ar in the relativistic treatment of the <(N)over bar N>- and NN-intera ctions. The partial wave analysis is performed in the framework of a r elativistic OBE quasipotential model, and the results are compared wit h those obtained in the nonrelativistic approximation.
