VizieR Online Data Catalog: Excitation rates for transitions in Ca XV (Aggarwal+, 2003)
Abstract
Collision strengths for transitions among the energetically lowest 46 fine-structure levels belonging to the (1s2) 2s22p2, 2s2p3, 2p4, and 2s22p3l configurations of Ca XV are computed, over a wide electron energy range below 300Ryd, using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2003, Comput. Phys. Comm., in preparation). Resonances in the threshold region have been resolved in a fine energy mesh, and excitation rates are determined over a wide electron temperature range below 107K. The results are compared with those available in the literature, and the accuracy of the data is assessed.
