DE+RE effective collision strengths from the IPIRDW approach over the DE ones from the RDW method at T e = 105.2 K. The horizontal axis values are the upper level of excitations. The squares, circles, up-triangles, down-triangles, diamonds, and crosses are the excitations from levels i = 1, 2, 3, 4, 5, and others, respectively.
