A formula for the fission fragment yield area in the coordinate system of the fragment total kinetic energy and of the fragment mass is presented. It was deduced along the lines of the multiexit- channel model of fission elaborated by Brosa, Grossmann and Müller. This formula was fitted to the fragment mass-, average total kinetic energy-, and variance distributions of the thermal neutron induced fission of 235U. The obtained parameters are compared with the theoretical predictions. Further improvements of the fragment yield representation are discussed.
