Is. Shapiro et Av. Smirnov, RELATIVISTIC APPROACH TO THE NEARTHRESHOLD PHENOMENA IN THE NUCLEON-ANTINUCLEON INTERACTIONS, Nuclear physics. B, 1997, pp. 52-57
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.
