The meson production by mesons in the low-energy limit has been re-examined in the frame of static model of the extended source theory. Using Feynman's technique the calculation has been performed up to fifth order in the coupling constant. The renormalization procedure is the same as developed and applied by Chew in meson-nucleon scattering processes. To reduce the Feynman diagram an approximation similar to that of the Tamm-Dancoff type has been used. The total cross section for charged and neutral pions from the pion-nucleon collision in T=3 / 2, J=3 / 2 state are obtained for incident meson energy 260 to 570 Mev. The theoretical results have been compared with those of Franklin, Barshay and others. Franklin's result that production of charged pions is higher than that of neutral pions in the cut-off theory is confirmed. The present calculation predicts the charged pion production of about 7 mb at 500 Mev against the available experimental cross section of a maximum of 10 mb at the same energy.
