Description (Abstract):
Collision strengths and maxwellian averaged rate coefficients have
been calculated for 10011 infrared, optical and ultraviolet
transitions among 142 fine structure levels in Fe II. Collision
strengths are calculated using the R-matrix method with a 38 term
close-coupling target expansion and for electron energies up to 10
rydbergs. Rate coefficients are tabulated at a wide range of
temperatures at which Fe II is abundant in plasma sources. A brief
discussion of the calculations, sample results, and comparison with
earlier works are given. The present rates for Fe II are expected to
find applications in the IR, O, and UV spectral diagnostics of
astrophysical objects and laboratory fusion plasmas
