| 英文摘要 | We have carried-out parallel intermediate-coupling frame transformation R-matrix calculations for electron-impact excitation amongst the 204 close-coupling levels of the 2s(x)2p(y) (x + y = 3), 2s(2) {3, 4}l, 2s2p{3, 4}l, and 2p(2)3l configurations for all boron-like ions from C+ to Kr31+. We have also included the configuration interaction due to the 2p(2)4l, 2s3l3l' and 2p3s3l configurations. A detailed comparison has been made of the target structure and excitation data for four specific ions (viz., Ne5+, Ar13+, Fe21+ and Kr31+) that span the sequence, so as to assess the accuracy over the entire sequence. Effective collision strengths (.s) are presented at temperatures ranging from 2x10(2)(z + 1)(2) K to 2x10(6)(z + 1)(2) K (where z is the residual charge of the ions, i.e. Z -5). Detailed comparisons for the (effective) collision strengths (Gamma s) Omega are made with the results of previous calculations for the four representative ions. Furthermore, we examine the iso-electronic trends of the effective collision strengths as a function of temperature. |
