Energy levels, oscillator strengths, and effective collision strengths for transitions in Fe XIV

Abstract

In this paper we report atomic data, namely energy levels, radiative rates, lifetimes, collision strengths, and excitation rate coefficients, for transitions among 162 levels of the (1s22s22p6) 3s23p, 3s3p2, 3s23d, 3p3, 3s 3p3d, 3p23d, 3s3d2, 3p3d 2, 3d3, 3s3p4s, and 3s24ℓ configurations of Fe XIV. For the calculations of energy levels and radiative rates both the grasp and fac codes have been adopted, whereas for the collision strengths only fac is employed. © 2009 IOP Publishing Ltd.
