Integral Cross Section for Electron-Impact Excitation of the 3p⁵3d States of Argon
Theoretical close-coupling R-matrix and two different first-order distorted-wave Born approximation (DWBA) calculations are presented for excitation of argon from its ground state to the twelve states in the (3p53d) manifold. The results are found to be very sensitive to the choice of atomic wavefunctions. The low-energy R-matrix results in general and, in several cases, the unitarized DWBA as well as the high-energy DWBA results are in fair agreement with the experimental data of Chilton and Lin (1999 Phys. Rev. A 60 3712).
