Abstract

Excitation of the 3 1P 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 pseudo-states 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 1P and 3 3P 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.
