A study is made of the light-cone behavior of the matrix element of the commutator of conserved currents between one-nucleon states at zero momentum transfer for the scalar gtuon model in the second order in the gluon-nucleon coupling constant and the principal singularity of this matrix element in the ladder approximation is also studied.
