摘要：

Using configuration interaction wavefunctions collision strengths OMEGA are calculated for transitions among the lowest 12 excited states of the (1s(2)2S(2)2p6) 3s2, 3p2, 3s3p, 3s3d, 3s4s and 3s4p configuration of Al II. The standard and no-exchange R-matrix programs are employed for computing the contributions of OMEGA for L less-than-or-equal-to 12 and L > 12 respectively. Pseudoresonances have been removed and the results are listed at 10 energies in the range 1.5 to 10 Ryd. A comparison of present results shows the earlier available collision strengths to be in error by over an order of 3 for some of the transitions. This error arose mainly in the computation of the contribution of OMEGA for L>6 in the earlier results. However, the differences are discussed and the accuracy of our present collision strengths is assessed.
