Accurate measurements of the 1000-eV noncoplanar symmetric (e,2e) reaction on argon are reported. Cross-section calculations are carried out with use of both the plane-wave and distorted-wave impulse approximations. The distorted-wave impulse approximation describes accurately both the 3p and 3s angular correlations and their relative cross sections. The plane-wave impulse approximation overestimates the 3s cross section relative to the 3p and underestimates cross sections at large angles. The 3s spectroscopic factors are assigned up to a separation energy of 55 eV and the distorted-wave impulse calculation verifies that all the 3s strength has been found.
