Based on the BBK theory, the influence of momentum correlation in the final state on the triple differential cross sections (TDCS) is considered. Then the TDCS for electron impact ionization of helium at a symmetric coplanar energy sharing geometry are calculated. An excellent agreement with the recent absolute measurement of helium is found in the present calculation, compared with other theoretical models.
