Electron impact excitation of Kr XXXII

Collision strengths ( Ω ) have been calculated for all 7750 transitions among the lowest 125 levels belonging to the 2 s 2 2 p, 2 s 2 p 2 , 2 p 3 , 2 s 2 3 ℓ , 2 s 2 p 3 ℓ , and 2 p 2 3 ℓ 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 ( ϒ ) have been obtained after averaging the values of Ω over a Maxwellian distribution of electron velocities. Values of ϒ are reported over a wide temperature range below 10 7.3 K , and the accuracy of the results is assessed. Values of ϒ are also listed in the temperature range 7.3 ⩽ log T e ( K ) ⩽ 9.0 , obtained from the nonresonant collision strengths from the Flexible Atomic Code.
