| Abstract: | A study is made of the behavior of the residues at the Regge poles of the partial-wave T matrix on the mass shell as a function of the energy E for nonrelativistic scattering on an exponential potential and two Yukawa potentials. It is shown that the residues do not have left-hand cuts in the E plane. |
