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
