We report numerical results for the triply differential cross sections (TDCS) for electron-impact ionization of helium in the Glauber approximation in the incident energy range 224.58--2824.58 eV. The present calculation is based upon the technique of Roy et al., which has an advantage over the conventional partial-wave method in calculating TDCS in that the latter requires substantial computer time where many partial waves are involved. A comparison is made of the present TDCS with the results of available theoretical calculations and absolute measurements.
