Isotope effects in the electron impact ionization of H2/D2, H2O/D2O and C6H6/C6D6 near threshold region were studied using high-resolution electron impact ionization mass spectrometer. The isotope shifts were determined for all the three systems ranging from a few meV for the parent ions to a few hundred meV for the fragment ions. It is found that the experimental result and the theoretical results are in good agreement with each other.
