The preceding Comment reports some low-energy electron-impact spectra of helium and ethylene, obtained by a very elegant technique, which are markedly different from the ones we obtained 1 under other experimental conditions. It is quite important to try to understand the reasons for the differences observed. These differences are essentially the following: (a) In our impact spectra of helium obtained with 50-eV electrons we observe pronounced peaks corresponding to the 2 ^3S state and to ionization whereas Simpson and Mielczarek do not. (b) In our spectra of ethylene at this same incident electron energy we observe two pronounced optically forbidden transitions and
