N2 - Cadmium [Formula Presented] energy spectra have been measured for incident electron energy 150 eV and scattering angles 2°–18°, corresponding to momentum transfer 0.2–1 a.u. This choice of kinematics covers the transition from the dipole limit at 0.2 a.u. to the binary collisions regime at 1 a.u. The data are presented as the sum and difference of pairs of [Formula Presented] spectra with ejected-electron directions 180° apart. This analysis reveals trends in the data and also provides a sensitive test of theory. Data sets for three special ejected-electron directions are compared with plane-wave Born approximation calculations. The calculated spectral shapes are in good agreement with all experiments when a simple phase correction is incorporated. The calculated difference/sum relative intensities are in good agreement with one data set but are in very poor agreement with the other two.
