Different types of vertex functions of a pion are investigated. The separable kernel of the quark-antiquark interaction is used to obtain an analytical solution of the equation. The pion constants and the form factors on both the on-shell and off-shell surfaces are calculated. The differential cross section of the reaction $^1H(e,e' \\pi^ +) n$ is also calculated in the paper. All the obtained results are compared with experimental data.
