The relative elastic differential cross-sections(EDCSs) of 2500eV electrons scattered by helium,neon and argon atoms were measured at a scattering angle range of 4°—15°.The absolute values of these EDCSs were obtained by normalizing the relative values to the known generalized oscillator strengths.The final results were compared with previous experimental and theoretical results.
