Abstract
Collision strengths (Ω) have been calculated for all 7750 transitions among the lowest 125 levels belonging to the 2s22p,2s2p2,2p3,2s23â,2s2p3â, and 2p23â configurations of boron-like krypton, Kr XXXII, for which the Dirac Atomic R-matrix Code has been adopted. All partial waves with angular momentum J⩽40 have been included, sufficient for the convergence of Ω for forbidden transitions. For allowed transitions, a top-up has been included in order to obtain converged values of Ω up to an energy of 500 Ryd. Resonances in the thresholds region have been resolved in a narrow energy mesh, and results for effective collision strengths (Ï) have been obtained after averaging the values of Ω over a Maxwellian distribution of electron velocities. Values of Ï are reported over a wide temperature range below 107.3K, and the accuracy of the results is assessed. Values of Ï are also listed in the temperature range 7.3⩽logTe(K)⩽9.0, obtained from the nonresonant collision strengths from the Flexible Atomic Code.
