On the Regge poles for superposition of central and spinorbit potentials

Nature of arrangement, multiplicity factor and behaviour of the Regge poles, when the Schroendinger eguation besides the central potential takes account of also spin-orbital potential have been investigated. It is established that in this case the appearance of additional poles in the Relambda>0 region are possible, which may be interpreted as bound states and resonances. The Regge poles can be both in the first and in the fourth quadrants of lambda plane at K2>0. In the case of sign-constant spin-orbital potential in consequence of comparison of the number of bound states and system resonances at j=l+1/2 and j=l-1/2, it is possible to determine the sign of spin-orbital potential
