N2 - Atomic collision parameters have been derived for electron impact excitation of calcium using the superelastic scattering method, at incident energies equivalent to 20, 25 and 35 eV. The pseudo-Stokes parameters for the superelastic process were determined, and the parameters Plin+, L⊥+, γ+ and Ptot+ derived for the 4 1P1 state. The results are compared to a relativistic distorted-wave approximation (RDWA) theory, and to previous experimental results. At the highest incident energy the results presented here compare well with theory, but at the lowest energy, significant disagreement between theory and experiment is observed.
