Use of the factorized form for the collision strength in exploration of the effect of the generalized Breit interaction

Physical Review A, 1994
Expressions are given for the convenient factorized form [Bar-Shalom, Klapisch, and Oreg, Phys. Rev. A 38, 1773 (1988)] for the collision strength with inclusion of the generalized Breit interaction. This is used to explore further the importance of the inclusion of the generalized Breit interaction in calculating electron-impact excitation cross ...

Effective collision strengths among the fifteen lowest states of FeXVII

Pramana, 1993
Collision strengths have been calculated for electron impact excitation of neon-like Fe XVII for all transitions within its 15 lowest states. Configuration interaction wavefunctions have been used to represent the target states. The standardR-matrix code has been used to calculate the contribution from the lower scattering partial waves (L⩽9), while ...

Effective Collision Strengths for Transitions within the Ground Configuration of Fe XXI

Physica Scripta, 2001
Effective collision strengths for transitions among the energetically lowest 46 fine-structure levels belonging to the (1s2) 2s22p2, 2s2p3, 2p4, 2s22p3s, 2s22p3p and 2s22p3d configurations of Fe XXI are computed, over an electron temperature range of 5.6 ≤ log Te ≤ 7.4K, using the recent Dirac Atomic R-matrix Code (DARC) of Norrington and Grant ...
