摘要
We have used both non-relativistic and relativistic distorted-wave approximation methods to study the excitation of the 4(1)P(1) state of calcium from the ground 4(1)S(0) state. Calculations have been performed for the differential and integrated cross sections and Stokes parameters. The results are presented for electron impact energies in the range of 10-100 eV We compare our results with the recently reported experimental measurements of Milisavljevic et al (2004 J. Phys. B: At. Mol. Opt. Phys. 37 3571) and discuss the sensitivity of these results to the choice of wavefunctions and approximation method used.
