Electron excitation rates for iron ions

Abstract

Experimental and theoretical data for the electron impact excitation of Fe I to Fe XXVI have been assessed. On the basis of these assessments, a set of recommended rates has been produced for each species. The recommended data are presented in the form of tables of polynomial fit coefficients. An estimate of the accuracy is given for each recommended data set, and a bibliography for each ion species is also supplied.

“…The most important processes with the edge plasma electrons, eventually followed by radiative processes, are: e + A q+ (i) + hvy (12a) e + A q+ (1) -e + A q+ (j) \ e + A (q+1)+ (1) + hv V} (12b) e + A q+ (i) -e + A q+ (j); i > 1, j > i (13a) -e + A q+ (j); i > 1 (13b) e + A q+ (i) -e + A (q+1)+ (1) + e, i > 1 (14a) -e + A( q+1)+ (1) + e, i > 1 (14b) e + A q+ (1) -A (q -1)+ (i) + hv, i > 1 (15) e + A q+ (1) -A (q -1)+ (i, j) -A (q -1)+ (j) + hvjj (16) Covers data for the transitions 1 -2; 1 -3; 2 -2; 2 -• 3 having different accuracies (see Ref. [43]).…”
