“…4 and 5. The DCSs at 10 • scattering angle measured by Williams and Trajmar [3] (the errors are not given) are lower than ours by approximately 40% at E 0 = 10 and 20 eV, but higher by approximately 10% at 40 eV. A general conclusion from Figs.…”

“…Williams and Trajmar [3] measured cross sections for elastic scattering and several excitations including the resonance transition at impact energies of 10, 20 and 40 eV. At the same electron-impact energies, Brunger et al [4] determined DCSs for the 3s3p 1 P 1 state in the angular range from 5 • to 130 • at energies of 10 and 20 eV and from 3 • to 130 • at 40 eV in 1 • steps at small angles.…”

Excitation of the 3 1 P state of magnesium by 20 eV electrons has been studied experimentally using the scattered-electron-polarized-photon correlation method over a wide range of scattering angles (10• -120 • ) and theoretically using the convergent close-coupling and R-matrix with pseudostates methods. The measured linear Stokes parameters, and the circular polarization calculated from these parameters, assuming coherent excitation, are generally well produced by these theoretical models as well as by some previous theories. Relative differential cross sections for elastic scattering and excitation of the 3 1 P and 3 3 P states were also measured over the angular range 10• -140• . The results are compared with those from previous experiments and with present and previous theoretical predictions.

“…The previous measurements of Williams and Trajmar (1978) were subject to large (f50%) uncertainties in the cross sections. Thus it has not been possible to test the predictions of the theory.…”

A b s t n d . A modulated crossed beam technique has been used to measure the differential cross sections for the excitation of the 3'P state in magnesium by elecvons at impact energies of 10 and 20 eV. The cross sections ace measured over a range of scattering angles fmm IO to 130'.Our results agree with the previous exprimental cross sections of Williams and Trajmar within the combined uncertainties. however the present data reduce the uncenainty by almost an order of magnitude thereby allowing a meaningful comparison to be made with the predictions of the various theories. At this time no theory accurately predicts the behaviour of the cmss sections over the whole angular range.
