We report new investigations for the five differential cross section (FDCS) of the double ionization of methane by fast electron impact. The present study is performed within the first and second Born approximation. The target initial state is described by a single-center wave function of Moccia, while we represent the final state by using the approximate 3C model with the usual Gamow factor then with the Ward and Macek factor as a corrected version. The different mechanisms have been identified for specific kinematic conditions.
