Elastic and inelastic differential cross sections (DCS) of high energy electrons (25 keV) scattered by neon and argon have been separately measured by totally independent methods. The effects of electronic correlations on the DCS and on the radial distribution functions D(R) and P(R) are deduced from experiment by comparison with theoretical Hartree--Fock values. An estimate of the correlation energy is also given. In the case of neon, the differences, with respect to Hartree--Fock, of the various contributions to atomic potential energy ..delta.. Vne, ..delta.. Vee/sup Coul/, and ..delta..Vee/sup exch/ are calculated from experiment and compared to theoretical results.
