The triple-differential cross sections for the electron-impact ionization of helium in coplanar asymmetric geometry have been calculated by use of a second Born approximation which employs an improved choice for the target continuum-state wave function. The results are compared with the absolute experimental data of K. Jung et al. (J. Phys. B 18, 2955 (1985)) at an incident energy of 600 eV and are found to be in very good agreement with them. The corresponding results for the positron-impact case are also presented.
