Excitation of forbidden lines in gaseous nebulae - II. Calculations for 3pq ions

The formulation for electron collisions with ions in configurations 1s2 2s2 2p2 and 1s2 2s2 2p6 3s2 3qq has been given in paper I of the present series (Saraph, Seaton & Shemming 1969). The present paper gives results of numerical calculations for 3pq ions, made in the distorted wave approximation. Collision strengths are obtained for all inelastic transitions in the configurations 1s2 2s2 2p6 3s2 3pq, q = 1 to 5. Calculations are made for three different energies and for values of the residual change z in the range z = 1 to z = 15. Results may be interpolated for all members of the isoelectronic sequences up to nickel.
