Radiative Rates, Collision Strengths and Effective Collision Strengths for Transitions in Mo XXXIV

open access: yesPhysica Scripta, 2005
Radiative rates for electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transitions among the lowest 60 fine-structure levels of the (1s2) 2s22p5, 2s2p6, and 2s22p43l configurations of F-like Mo XXXIV have been calculated using the fully relativistic GRASP code.

Collision strengths for transitions of Ni XXI

open access: yesThe European Physical Journal D, 2013
In this paper, we use Dirac R-matrix theory to calculate the collision strengths for electron impact excitation of Ni XXI with the Dirac atomic R-matrix code (DARC), which includes contributions of resonances, channel coupling, and relativity. A DARC calculation has been performed for transitions among 86 levels of (1s 2) 2s

EFFECTIVE COLLISION STRENGTHS FOR ELECTRON-IMPACT EXCITATION OF S X

open access: yesAtomic Data and Nuclear Data Tables, 2000
Effective collision strengths computed by the R-matrix method are presented for the electron-impact excitation of nitrogen-like S X. The total wave function used in the expansion includes the lowest 11 eigenstates of S X which arise from the 2s(2)2p(3 ...

Collision strength and effective collision strength for Br XXVII

Canadian Journal of Physics, 2017
Collision strengths for all 1326 transitions among lowest 52 fine-structure levels of Br XXVII have been computed using Dirac atomic R-matrix code (DARC). Resonances in the threshold region have been completely resolved and the contributions of these resonances to allowed and forbidden transitions have been presented.

Collision strength and effective collision strength for Ba XLVIII

Canadian Journal of Physics, 2017
Collision strengths for the lowest 52 fine-structure levels of Ba XLVIII have been computed using Dirac atomic R-matrix code (DARC). Resonances in the threshold region have been completely resolved and the contributions of these resonances to allowed and forbidden transitions have been presented. Effective collision strengths have also been determined

Reply to the comment by K.M. Aggarwal on “Collision strength and effective collision strength for Ba XLVIII”

Canadian Journal of Physics, 2020
We show that the comment of K.M. Aggarwal (2018, Can. J. Phys. 96(10), doi: https://www.nrcresearchpress.com/doi/pdf/10.1139/cjp-2017-0842 ), although being only marginally relevant to the content of the original paper (2017, Can. J. Phys. 95(2), doi: https://www.nrcresearchpress.com/doi/pdf/10.1139/cjp-2016-0513 ), misinterprets our results and leads
